Panel mounting
Cut-out: 117 x 89mm (WxH)
(4.606”x 3.504”)
Note: Removing the unit requires clearance space. Recommendation: approximately 40mm (1.58”).
For UL listed module, in order to meet the UL508 standard, panel-mount this device on
the flat surface of a Type 1 enclosure.
Wiring
Note: All diagrams are based on the rear view of the OPLC.
This equipment is designed to operate only in SELV/PELV/Class 2/Limited Power
environments.
All power supplies in the system must include double insulation. Power supply 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.
Do not touch live wires.
All wiring activities should be performed while power is OFF.
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, use 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 mm² –0.13 mm² wire (12-26 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.
Wiring Guidelines
Use separate wiring ducts for each of the following groups:
oGroup 1: Low voltage I/O and supply lines, communication lines.
oGroup 2: High voltage Lines, Low voltage noisy lines like motor driver outputs.
Separate these groups by at least 10cm (4"). If this is not possible, cross the ducts at a 90˚angle.
For proper system operation, all 0V points in the system should be connected to the system 0V
supply rail.
Allow for voltage drop and noise interference with input lines used over an extended distance. Use
wire that is properly sized for the load.
Earthing the JZ20-R31/JZ20-J-R31
To maximize system performance, avoid electromagnetic interference as follows:
Use a metal cabinet.
Connect the 0V terminal directly to the earth ground of the system.
Use the shortest, less than 1m (3.3 ft.) and thickest, 2.08mm² (14AWG) min, wires possible.
Inputs
This model comprises a total of 20 inputs in 3 groups.
1. I0 to I15 are digital inputs. They may be wired, in a group, as either npn or pnp.
2. I16 and I17 may be wired as either digital or analog inputs. These may be wired as either:
npn digital inputs
pnp digital inputs
analog (voltage) inputs
In addition, 1 input may be wired as a pnp input, while the other is wired as an analog input.
Note that if 1 input is wired as an npn input, the other may not be wired as an analog input.
3. AN0 and AN1 are analog (current) inputs that may be wired using 2, 3, or 4 wires.

Digital Inputs, Controller’s Power Supply
Note: The inputs are arranged in two groups. You can wire one group as npn and the other as pnp,
or wire both groups as npn, or as pnp. In either case, the npn/pnp pins must be connected.

Increasing contact life span
To increase the life span of your contacts and protect the unit 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
Analog inputs
Note: Shields should be connected at the signal source.
Analog Input wiring, current (AN0-AN1)
2 or 3-wire
4-wire
Analog Input wiring, voltage (AN2-AN3)
Note: If either I16 or I17 is wired as an npn digital input, the remaining input may not be wired as an
analog input.
