the dimensions in the figure to the
right.
2. Slide the controller into the cut-
out, ensuring that the rubber seal
is in place.
3. Push the 8 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.
Note: For UL listed module, in order to meet the UL508 standard, panel-mount this device

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 mm 2–3.31 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.
Power Supply
The controller V1210-T20BJ requires either an external 12 or 24VDC power supply.
Permissible input voltage range: 10.2-28.8VDC, with less than 10% ripple.
▪ The power supply must include double insulation. Outputs must be rated as
SELV/PELV/Class 2/Limited Power.
▪ Do not connect either the ‘Neutral or ‘Line’ signal of the 110/220VAC to device’s 0V pin.
▪ Install an external circuit breaker. Guard against short-
circuiting in external wiring.
▪ Double-check all wiring before turning on the power
supply.
▪ In the event of voltage fluctuations or non-conformity to
voltage power supply specifications, connect the device
to a regulated power supply.
Earthing the OPLC
To maximize system performance, avoid electromagnetic interference by:
▪ Mounting the controller on a metal panel.
▪ Connect the functional earth terminal of the OPLC, and the common and ground lines of
I/Os, directly to the earth ground of your system.
▪ For ground wiring, use the shortest and thickest possible wire.

Communication Ports
This series comprises a USB port, 2 RS232/RS485 serial ports and a CANbus port. An additional
port may be ordered separately and installed. This port may be either Ethernet, or serial (COM 3).
For the most updated information regarding ports and their installation, please refer to the Technical
Library at www.unitronics.com.
▪ Turn off power before making communications connections.
Caution
▪ Always use the appropriate port adapters.
The USB port may be used for programming, OS download, and PC access.
Note that COM port 1 function is suspended when this port is physically connected to a PC.
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.
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 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).

RS232 to RS485: Changing DIP Switch Settings
The ports are 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
switches according to the following table.

2. Line the circular guidelines on the Snap-in I/O Module with the slots on the controller 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.
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.

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.
