Wiring
Note: All diagrams are based on the rear view of the OPLC.
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.
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.
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm
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.
Inputs
This model comprises a total of 10 inputs in 3 groups.
1.
I0 to I5 are digital inputs. They may be wired, in a group, as either npn or pnp.
2.
I6 and I7 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 (voltage) inputs.
