3. Replace the battery cover.

Mounting

Dimensions

Note that the LCD screen may have a single pixel that is permanently either black or white.

Panel Mounting

Before you begin, note that the mounting panel cannot be more than 5 mm thick.

1. Make a panel cut-out according to the dimensions in the figure to the right.

2. Slide the controller into the cutout, ensuring that the rubber seal is in place.

3. Push the 4 mounting brackets into their slots on the sides of the controller as shown in the figure to the right.

4. Tighten the bracket screws against the panel. Hold the bracket securely against the unit while tightening the screw.

5. When properly mounted, the controller is squarely situated in the panel cut-out as shown below.
   

Wiring

• Do not touch live wires.

• Install an external circuit breaker. Guard against short-circuiting in external wiring.

• Use appropriate circuit protection devices.

• Unused pins should not be connected. Ignoring this directive may damage the device.

• Double-check all wiring before turning on the power supply.

Caution

• 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 substance on stripped wire that might cause the wire strand to break.
• Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure

Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm2–3.31 mm2 ).

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 a proper connection.
4. Tighten enough to keep the wire from pulling free.
   • 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.

I/Os

This model comprises a total of 16 digital inputs, 2 analog inputs and 16 outputs.

1. Input functionality can be adapted as follows:
   All 16 inputs may be used as digital inputs. All 16 may be wired in a group, via a pin on the connector, as either npn or pnp. In addition, according to jumper settings and appropriate wiring:

   • Inputs 160 & 162 can function as either a high-speed counter, as part of a shaft-encoder, or as a normal digital input
   • Inputs 161 & 163 can function as either a counter reset, as part of a shaft-encoder, or as a normal digital input
   • If inputs 160 & 162 is set as a high-speed counter (without reset), inputs 161 & 163 can function as normal digital inputs

2. Output functionality is as follows:

   • All 15 (161-175) outputs are pnp outputs
   • Output 160 is an npn – High Speed Output

• Shields should be connected at the signal’s source.
• Analog inputs are not isolated. They relate to the controller’s main power supply.

Output Wiring

Power Supply

The controller and the digital IO require an external 24VDC power supply.

• A non-isolated power supply can be used if a 0V signal is connected to the chassis.

• Install an external circuit breaker. Guard against short-circuiting in external wiring.

• Double-check all wiring before turning on the power supply.

• Do not connect either the ‘Neutral or ‘Line’ signal of the 110/220VAC to device’s 0V pin.

• In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

Earthing the Power Supply

To maximize system performance, avoid electromagnetic interference by:

• Mounting the controller on a metal panel.
• Earthing the controller’s power supply: connect one end of a 14 AWG wire to the chassis signal; connect the other end to the panel.

Note: If possible, the wire used to earth the power supply should not exceed 10 cm in length. However, it is recommended to earth the controller in all cases.

Communication Port

This series comprises 2 RS232/RS485 serial ports and a CANbus port.

• Turn off power before making communications connections.

Caution

• Always use the appropriate port adapters.

The serial ports are type RJ-11 and may be set to either RS232 or RS485 via DIP switches, in accordance with the table shown below.

By factory default, the port is set to RS232, termination ON.

• Use RS232 to download programs from a PC, and to communicate with serial devices and applications, such as SCADA.
• Use RS485 to create a multi-drop network containing up to 32 devices.

Pinouts

The pinouts below show the PLC port signals.

To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC to the PLC via the programming cable. Note that this is possible only if flow control signals are not used (which is the standard case).

*Standard programming cables do not provide connection points for pins 1 and 6.
**When a port is adapted to RS485, Pin 1 (DTR) is used for signal A, Pin 6 (DSR) signal for signal B.

Removing a Snap-in I/O Module

1. Locate the four buttons on the sides of the controller, two on either side.
2. Press the buttons and hold them down to open the locking mechanism.
3. Gently rock the module from side to side, easing the module from the controller.

Re-installing a Snap-in I/O Module

1. Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O Module as shown below.
2. 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.

CANbus

These controllers comprise a CANbus port. Use this to create a decentralized control network using one of the following CAN protocols:

• CANopen: 127 controllers or external devices
• CANLayer 2
• Unitronics’ proprietary UniCAN: 60 controllers, (512 data bytes per scan)

The CANbus port is galvanically isolated.

CANbus Wiring

Use twisted-pair cable. DeviceNet® thick shielded twisted pair cable is recommended.

Network terminators: These are supplied with the controller. Place terminators at each end of the CANbus network.

Resistance must be set to 1%, 121Ω, 1/4W.

Connect ground signal to the earth at only one point, near the power supply.

The network power supply need not be at the end of the network

CANbus Connector

Technical Specifications

Notes:

3. Maximum current consumption does not provide for pnp output requirements.
The additional current requirement of pnp outputs must be added.

Notes

4. Input functionality can be adapted as follows:
All 16 inputs may be used as digital inputs. All 16 may be wired in a group, via a pin on the connector, as either npn or pnp. In addition, according to jumper settings and appropriate wiring:

Inputs 160 & 162 can function as either a high-speed counter, as part of a shaft-encoder, or as a normal digital input

Inputs 161 & 163 can function as either a counter reset, as part of a shaft- encoder, or as a normal digital input

If inputs 160 & 162 is set as a high-speed counter (without reset), inputs 161 & 163 can function as normal digital inputs

5. The digital inputs and outputs are not isolated from each other. They are isolated from the analog inputs and from the controller.

6. If you configure an input as high-speed, you can use an end-device that comprises push-pull drive type. In this case, the high-speed input voltage ratings for npn/pnp apply.

Notes:

8. The standard for each port is set to either RS232/RS485 according to DIP switch settings. Refer to the Installation Guide.
