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 mm²
–0.13 mm² wire (12-16 AWG):
1. Strip the wire to a length of 7±0.5mm (0.275±0.020
“).
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 model and I/O signals must be connected to the same 0V signal.
I/Os
This model comprises a total of 9 digital inputs, 2 relay outputs and 4 npn (sink) outputs. Input
functionality can be adapted as follows:
1. The digital inputs may be wired, in one group, and set to either npn or pnp via wiring.
In addition, according to appropriate wiring:
- 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 and 4 are set as high-speed counters (without reset), inputs 1, 3 and 5
can function as normal digital inputs.
