Mounting
Dimensions
Panel Mounting
Before you begin, note that the mounting
panel cannot be more than 5 mm thick.
1. Make a panel cut-out measuring
92x92 mm (3.622”x3.622”).
2. Slide the controller into the cut-out,
ensuring that the rubber seal is in place.
3. Push the 2 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 in the figure to the right.

DIN-rail Mounting
1. Snap the controller onto the DIN
rail as shown in the figure to the
right.
2. When properly mounted, the
controller is squarely situated on
the DIN-rail as shown in the figure
to the right.
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 mm
2
):
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.
The controller and I/O signals must be connected to the same 0V signal.
Connect cable shields to the system earth ground using the shortest and thickest possible wire.

I/Os
This model comprises a total of 12 inputs 6 relay and 2 npn outputs. Input functionality can be
adapted as follows:
1. 12 inputs may be used as digital inputs. They may be wired in a group via a single jumper
as either npn or pnp.
According to jumper settings and appropriate wiring:
- Inputs 10 and 11 can function as either digital or analog inputs.
- Inputs 0, 2, and 4 can function as high-speed counters, as part of a shaft-encoder,
or as normal digital inputs.
- Inputs 1, 3, and 5 can function as either counter reset, as part of a shaft-encoder,
or as normal digital inputs.
- If inputs 0, 2, 4 are set as high-speed counters (without reset), inputs 1, 3, 5 can function as
normal digital inputs.
Input Jumper Settings
The tables below show how to set a specific jumper to change input functionality. To access the I/O
jumpers, you must open the controller according to the instructions beginning on page 9.
Incompatible jumper settings and wiring connections may seriously damage the controller.

Shields should be connected at the signal’s source.
The 0V signal of the analog input must be connected to the controller’s 0V.
Relay Outputs
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

npn Outputs
Power Supply
The controller requires an external 24VDC power supply.
The power supply must include double insulation. Outputs must be rated as
SELV/PELV/Class 2/Limited Power.
Use separate wires to connect the
functional earth line
(pin 3) and the 0V line (pin 2) to the system earth
ground.
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 OPLC
To maximize system performance, avoid electromagnetic interference by:
Mounting the controller on a metal panel.
Connect each common and ground connection directly to the earth ground of your system.
For ground wiring use the shortest and thickest possible wire.
Communication Port
Turn off power before making communications 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 port is not isolated. If the controller is used with a non-isolated external device,
avoid ground potential difference that exceeds ± 10V.
Port 1 is type RJ-11 and may be set to either RS232 or RS485 via jumper as 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).

RS232 to RS485 Jumper Settings
The figure to the right shows the jumper
factory default settings, RS232, RS485
termination ON.
Note that in order:
To change the communication
setting to RS485, both
communication standard jumpers
must be moved.
To change the RS485 termination,
both termination jumpers must be
moved.
To access the jumpers, you must open the
controller according to the instructions
below.
Opening the Controller
Before performing these actions, touch a grounded object to discharge any electrostatic
charge.
Avoid touching the PCB board directly. Hold the PCB board by its connectors.
1. Turn off the power supply, disconnect, and dismount the controller.
2. The back cover of the controller comprises 4 screws, located in the corners. Remove the screws,
and pull off the back cover.

Changing I/O settings
1. The I/O board of the controller is now exposed, enabling you to change I/O settings according to
the jumpers shown on page 5.
Changing Communication Settings
1. To access the communication
jumpers, locate the screw close to
COM port 1, and remove it.
2. Hold the I/O PCB board by its top and
bottom connectors and steadily pull
the board off.
3. Locate the jumpers, and then change
the settings as required. Jumper
settings are shown on page 9.
Closing the Controller
1. Gently replace the board. Make
certain that the pins fit correctly into
their matching receptacle.
Do not force the board into place;
doing so may damage the controller.
2. Replace the back cover of the
controller and fasten the corner
screws.
Note: You must replace the back cover securely before powering up the controller.
