Introduction

• The ETS Lindgren EMSwitch™ RF Switch Plug in Card is a general purpose multi-channel switch matrix used to switch the RF path of equipment for RF measurement applications, including immunity, emissions, and wireless measurements. EMSwitch is designed for use with the EMCenter™ Modular RF Platform.
• The first relay of each EMSwitch card can be used as a standard relay or as a safety interlock relay. When being used as a safety interlock relay, the RF input signal to the RF amplifier can be switched off to prevent personnel from being subjected to high RF fields. For example, the RF interlock input can be connected to a switch mounted on the entrance door of the test chamber.

Standard Configuration
Standard configuration may vary by model; contact ETS-Lindgren for additional information.

• EMCenter Modular RF Platform
  Some Models may require a specific processor; See Processor Requirements for more information.

• EMSwitch Plug-In card
  EMSwitch cards switch RF signals up to 40 GHz, depending on the model, with powers up to 240 W (3 GHz) directly or any RF power switches indirectly. When high power RF amplifiers are used in a test system, the EMSwitch card can be connected to an optional EMSwitch Remote Relay Module.

• Interlock
  When one of the relays is used as a safety interlock relay, it can be used to switch of the RF input signal to the RF amplifier. A switch mounted on the entrance door of the test chamber can for example, activate the RF interlock input. This can prevent personnel from being subjected to high RF fields. This interlock input is fully integrated in the hardware; software cannot overwrite this safety system.

Remote Relay

• CAUTION: Before placing into operation, follow the information provided in Safety Information document.
• For applications that require to switch higher power signals (>700 Watts), it is not possible to use internal relays of the switch cards; in those cases, special dedicated relays are needed in the test setup. For these external relays, EMSwitch™ Model 7001 004 Remote Relay, which is capable of driving two external relays, is available.
• Model 7001 004 can drive any relay with a supply voltage of 12V, 24V, or 28V, and from SPDT to SP6T. For each relay a driver current of 0.5A is available, or 1A if only one relay is connected.
• The type of relay and the usage of indicator contacts can be configured in software. The connection for relay 1 and relay 2 are identical.

Front and Back Panel Connectors

• The front panel includes a key switch and an LED. If the EMSwitch™ Remote Relay is connected to a 220 V AC power supply and the on/off switch on the back panel is set to the I position, you can power on the remote relay by turning the key clockwise. The LED will illuminate.
• The Remote Relay must be connected to a 220 V AC power supply via the mains lead, connected at the AC inlet on the back panel.

Relays

• You can connect four relays to the remote relay. It is possible to connect relays with 1 input and 2, 3, 4, 5, or 6 outputs.
• To connect external relays you must use the mating connector set included with the remote relay.
• The relay x drive connectors on the back panel of the remote relay will switch the relays into position.
  • For a 24 V relay, connect pin 1 (24 V DC output) to the Common of the relay power terminals.
  • For a 12 V relay, connect pin 2 (12 V DC output) to the Common of the relay power terminals.
  • Connect pin 3–8 to the power terminals 1–6 of the relay.
• The number of power terminals to connect depends on the type of relay you use. For example, a 1–6 relay requires all of the pins, and a 1–3 relay requires three pins.

Readback Function
The relay x readback connectors on the back panel remote relay can verify if the external relay is set into position.

1. Connect pin 1 (3v3 out) to the indicator common of the relay.
2. Connect pin 2 to the first indicator of the relay.
3. Connect pin 3 to the second indicator; continue until complete.

The number of indicator terminals to connect depends on the type of relay you use. Pin 8 is not in use.
Set the readback function on or off in the EMCenter™ Modular RF Platform depending on the number of relay(s) with readback function that you use.

Set Up RS 232 Address
You can connect up to four external switch boxes to one EMCenter. Interconnect the switch boxes with straight RS 232 cables. The DIP switches on the back panel of the EMCenter allow you to set the individual addresses.

SPDT Connections

• The connections of the SPDT (Single Pole Double Throw) relays are marked with “NO”, “COM” and “NC” for respectively Normally Open, Common, and Normally Closed.
• These terms indicate the position of the relay. When not activated, the relay connects the COM to the NC connector. When energized, the relay connects the COM to the NO connector.

SP6T Connections
The center connector is the COM (Common). The other connections are numbered from one to six; this is visible in the illustration below and on the relay itself.

External Relay Plug-In Card

When the models with internal relays do not fit the needs (E.G. high-power switching), there is the 7001-004; this plug-in card is designed to use with external relays and can drive up to two (2) SP6T relays. It provides a user selectable supply of 12V, 24V, or 28V, with a maximum current of 0.5A per relay (voltage independent). The 7001-004 is also equipped with indicator contacts; these can provide feedback to the user on the state of the relay.

• Connector
  • The 7001-004 is shipped with four (4) connectors* to mate with the plug-in card connectors. A 2×8-way terminal block is used for each relay driver. The left row is used for energizing the coils (please note that only one coil can be active at a time).
  • The right row is used for the readback contacts of the relays. The connections for the indicator contacts are optional and can be enabled or disabled in the configuration screen of the switch card.
• Coil connections
  • The relay coil(s) must be connected on the left row between the V+ (common) and one of the six coil connections. The V+ is a user selectable 12V, 24V, or 28V.
  • The voltage can be set in the configuration screen of the plug-in card.
  • WARNING: Make sure that the correct voltage is set before connecting the relay. Wrong settings may result in permanent damage to the relay!
  • The coil connections are open collector outputs, which connect the coil to ground when, activated, thus energizing the relay coil.
• Indicator connections
  • Some relays are equipped with indicator contacts; these contacts indicate the position of the relay. The indicator contacts can be connected on the right row. The indicator contacts can be connected between the +3.3V and the corresponding input channel (the input channel corresponds to the same coil number).
• Interlock
  • The interlock connector provides two floating contacts, which require shorting for the first relay.
  • If the interlock is open, the first relay will illuminate red on the EMCenter™ Modular RF Platform screen and the relay cannot be used. Use the supplied connector to wire to the emergency switch of your site. Connect the two pins of the connector.
  • Note: For replacement interlock connectors, contact ETS-Lindgren to order part number 1608925.

Touchscreen

• Home Screen To change relay position settings, on the Home screen press the status box to the right of the slot number for the installed EMSwitch plug in card. This will display the following switch screen:
• EMControl Main Settings Screen
  • (COM — Common; NO — Normally Open; NC — Normally Closed)
  • Press a switch button (switch A, switch B, and so on) to toggle between NO and NC. In case of a failure, an error will be displayed in the screen.
• Safety Interlock Relay
  • Relay A on each EMSwitch plug in card can be used as a safety interlock relay. As long as the connector is shorted (by an external interlock switch), the relay can be activated.
  • However, as soon as the interlock circuit opens, relay A will return to the idle position.
  • Note: If you do not want to use this relay as a safety relay, the connector must be shorted in order to use it as a standard relay.
  • When the safety interlock relay is activated, the power supply to the first relay of the card will be interrupted (fully hardware controlled), causing the relay to switch to the normally open position. The EMCenter will detect this interlock status and display a message. For safety reasons, the software is not able to overrule this interlock condition.
  • After the interlock has been closed again, the relay will switch automatically to its original condition.
• Sample Interlock Error Screen
  The interlock hardware is implemented in a redundant way for maximum safety. The interlock relay can be used to interrupt the signal path between the signal generator and the power amplifier. An interlock switch mounted on the door of the test chamber can be used to activate the safety relay, preventing personnel from being subject to high field strengths when entering the test chamber.

Relay Errors
The EMSwitch plug in card checks for the following error conditions of the internal relays:

1. Over temperature — A temperature sensor close to each relay checks for excessive heating of the relay. A high temperature error will display if the relay temperature exceeds 85°C (185°F).
2. Relay errors — The EMSwitch checks the following error conditions of the internal relays.
3. Switching error — Each internal relay has a set of control contacts, which are used to check if a relay has changed position. A switching error message will appear if this check fails.
4. Interlock open for safety interlock relay — When the interlock of relay A is opened, this will result in a safety interlock open error.

To use the EMSwitch remote commands, read the manual document 399342 EMCenter for examples and a full command list.
