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 the 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).
- Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
- Unscrew the terminal to its widest position before inserting a wire.
- Insert the wire completely into the terminal to ensure a proper connection.
- 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.
Power Supply
The controller requires an external 12 or 24VDC power supply. The permissible input voltage range is 10.2-28.8VDC, with less than 10% ripple.
| ▪ 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 the
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 Ports
**** | ▪ Turn off power before changing communication settings or connections. |
---|---|
Caution | ▪ Signals are related to the controller’s 0V; the same 0V is |
used by the power supply.
▪ Always use the appropriate port adapters.
▪ The serial ports are not isolated. If the controller is used with a non-
isolated external device, avoid potential voltage that exceeds ± 10V.
Serial Communications
This series comprises 2 RJ-11-type serial ports and a CANbus port.
COM 1 is RS232 only. COM 2 may be set to either RS232 or RS485 via jumper as
described on page 9. By default, the port is set to RS232.
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 signals sent from the controller to the PC.
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, and Pin
6 (DSR) signal is used for signal B.3
RS232 to RS485: Changing Jumper Settings
The port is set to RS232 by factory default.
To change the settings, first remove the Snap-in I/O Module, if one is
installed, and then set the jumpers according to the following table.
****▪ Before you begin, touch a grounded object to discharge any
electrostatic charge.
▪ Before removing a Snap-in I/O Module or opening the controller, you must
turn off the power.
RS232/RS485 Jumper Settings
Jumper | 1 | 2 | 3 | 4 |
---|---|---|---|---|
**RS232*** | A | A | A | A |
RS485 | B | B | B | B |
RS485 Termination | A | A | B | B |
Removing a Snap-in I/O Module
- Locate the four buttons on the sides of the controller, two on either side.
- Press the buttons and hold them down to open the locking mechanism.
- Gently rock the module from side to side, easing the module from the controller.
Re-installing a Snap-in I/O Module
- Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O Module as shown below.
- 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
- CAN layer 2
- Unitronics’ proprietary UniCAN: 60 controllers, (512 data bytes per scan)
The CANbus port is galvanically isolated.
CANbus Wiring
Use a 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
