Wiring

• Do not touch live wires.
• Unused pins should not be connected. Ignoring this directive may damage the device.
• Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.
• Double-check all wiring before turning on the power supply.

Wiring Procedures
Use crimp terminals for wiring; use 26-12 AWG wire (0.13mm2 –3.31mm 2 ) for all wiring purposes.

1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure that a proper connection can be made.
4. Tighten enough to keep the wire from pulling free.
   ▪ To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).
   ▪ Do not use tin, solder, or any other substance on stripped wire that might cause the wire strand to break.
   ▪ Install at maximum distance from high-voltage cables and power equipment.

I/O Wiring—General

• Input or output cables should not be run through the same multi-core cable or share the same wire.
• Allow for voltage drop and noise interference with input lines used over an extended distance.
  Use wire that is properly sized for the load.

Earthing the product
To maximize system performance, avoid electromagnetic interference as follows:

• Use a metal cabinet.
• Connect the 0V and functional ground points (if exist) directly to the earth ground of the system.
• Use the shortest, less than 1m (3.3 ft.) and thickest, 2.08mm² (14AWG) min, wires possible.

Digital Inputs
Each group of 9 inputs has a common signal. Each group can be used as either pnp (source) or npn (sink), when appropriately wired as shown in the following figures.

• Inputs I0 and I2 can be used as normal digital inputs, as high-speed counters, or as part of a shaft encoder.
• Inputs I1 and I3 can be used as normal digital inputs, as high-speed counter resets, or as part of a shaft encoder.

Inputs I0, I1, and I2, I3 can be used as shaft encoders as shown below.

Digital Outputs

Wiring Power Supplies
Use a 24VDC power supply for both relay and transistor outputs.

1. Connect the “positive” lead to the “V1” terminal, and the “negative” lead to the “0V” terminal.
   ▪ In the event of voltage fluctuations or nonconformity to  voltage powersupply specifications, connect the device to a regulated power supply.

Relay Outputs

• Each group can be wired separately to either AC or DC as show.
• The 0V signal of the relay outputs is isolated from the controller’s 0V signal.

Increasing Contact Life Span
To increase the life span of the relay output contacts and protect the device from potential damage by reverse EMF, connect:

• a clamping diode in parallel with each inductive DC load,
• an RC snubber circuit in parallel with each inductive AC load.

Transistor Outputs

• Each output can be wired separately as either npn or pnp.
• The 0V signal of the transistor outputs is isolated from the controller’s 0V signal.

Analog Inputs

5 analog inputs:

• Inputs 0 to 2 can be wired to work with either current or voltage.
• Inputs 3 and 4 can function as either analog, RTD, or thermocouple, when appropriately wired as shown in the following figures.
  To configure an input, open the device and set the jumpers according to the instructions beginning on page 8. Shields should be connected at the signal source.

Analog Inputs

• When set to current/voltage, all inputs share a common ACM signal, which must be connected to the 0V of the controller.

RTD Inputs

• PT100 (Sensor 3): use both inputs related to CM3 signal.
• PT100 (Sensor 4): use both inputs related to CM4 signal.
• 4 wire PT100 can be used by leaving one of the sensor leads unconnected.

Thermocouple Inputs

• Supported thermocouple types include B, E, J, K, N, R, S, and T, in accordance with software and jumper settings. See table, Thermocouple Input Ranges, on page 13.
• Inputs may be set to mV by software settings (Hardware Configuration); note that in order to set mV inputs, thermocouple jumper settings are used.
• To ensure proper performance, a warm-up period of a half an hour is recommended.

Analog Outputs Power Supply

Use a 24VDC power supply for all analog output modes.

1. Connect the “positive” cable to the “V2” terminal, and the “negative” to the “0V” terminal.
   ▪ In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.
   ▪ Since the analog I/O power supply is isolated, the controller’s 24VDC power supply may also be used to power the analog I/Os.

The 24VDC power supply must be turned on and off simultaneously with the controller’s power supply.

Analog Outputs

• Shields should be earthed, connected to the earth of the cabinet.
• An output can be wired to either current or voltage, use the appropriate wiring as shown below.
• Do not use current and voltage from the same source channel.

Changing Jumper Settings

To access the jumpers, you must remove the snap-in I/O module from the controller, and then remove the module’s PCB board.

• Before you begin, turn off the power supply, disconnect and dismount the controller.
• Before performing these actions, touch a grounded object to discharge any electrostatic charge.
• Avoid touching the PCB board directly by holding the PCB board by its connectors.

Accessing the Jumpers
First, remove the snap-in module.

1. Locate the 4 buttons on the sides of the module, 2 on either side. Press the 2 buttons on either side of the module as shown, and hold them down to open the locking mechanism.

2. Gently rock the module from side to side, easing the module from the controller.
   

3. Using a Philips screwdriver, remove the center screw from the module’s PCB board.

Select the desired function by changing the jumper settings according to the figure and tables shown below.

| Jumper #| Voltage| Current
---|---|---|---
Analog input 0| 3| V| I
Analog input 1| 2| V| I
Analog input 2| 1| V| I
| Jumper #| Voltage| Current| TIC or mV| PT1 00
---|---|---|---|---|---
Analog input 3| 5| AN| AN| PT-TC| PT-TC
7| V| I| V| V
Analog input 4| 4| AN| AN| PT-TC| PT-TC
6| V| I| V| V

• Default factory setting

Reassembling the controller

1. Return the PCB board to the module and secure the center screw.
2. Next, reinstall the module. Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O Module as shown below.
3. Apply even pressure on all 4 corners until you hear a distinct ‘click’. The module is now installed. Check that all sides and corners are correctly aligned.
