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 3.31 mm ² –0.13 mm² wire (12-16 AWG):
1.Strip the wire to a length of 7±0.5mm (0.270–0.300“).
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 I/O 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.
I/Os
SM43-J-R20/SM35-J-R20 comprises a total of 12 inputs and 8 relays.
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 5 and 6 can function as either digital or analog inputs.
•If the digital inputs function as npn, analog option is not available.
- Input 0 can function as a high-speed counter, as part of a shaft-encoder, or as a normal
digital input.
- Input 1 can function as either a counter reset, normal digital input, or as part of a
shaft-encoder.
- If input 0 is set as a high-speed counter (without reset), input 1 can function
as a normal digital input.
SM43-J-T20/SM35-J-T20 comprises a total of 12 inputs and 8 transistor 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.

Opening the Controller
Note: Photo is for illustration purposes only. (Using SM43)
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, disconnects, and
dismounts 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 above.
Closing the Controller
1.Replace the back cover of the controller and fasten the corner screws.
Note that you must replace the back cover securely before powering up the controller.

Increasing Contact Life Span
SM43-J-R20/SM35-J-R20- Only
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
Power Supply
The controller requires an external 24VDC power supply.
Note: Photo is for illustration purposes only.
1. The power supply must include double insulation. Outputs must be rated as
SELV/PELV/Class 2/Limited Power.
2. Use separate wires to connect the functional
earth line (pin 3) and the 0V line (pin 2) to the
system earth ground.
3. Install an external circuit breaker. Guard
against short-circuiting in external wiring.
4. Double-check all wiring before turning
on the power supply.
5. Do not connect either the ‘Neutral’ or ‘Line’
signal of the 110/220VAC to device’s 0V pin.
6. 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
Always use the appropriate port adapters.
SM43-J-R20/SM43-J-T20
This series comprises a USB port.
Caution
The USB port is not isolated. Make sure that the PC and the controller are grounded to
same potential.
The USB port may be used for programming, OS download, and PC access.
SM35-J-R20/SM35-J-T20
This series comprises a build-in RS232 port.
Caution
Signals are related to the controller’s 0V; the same 0V is used by the power supply.
The serial port is not isolated. If the controller is used with a non-isolated external device,
avoid potential voltage that exceeds ± 10V.
Use RS232 to download programs from a PC, and to communicate with serial devices and
applications, such as SCADA.
