4.1.7 Wiring Digital Output Terminals on CPU Modules
Use single-wire cables or two-wire cables in a diameter of 24 AWG to 12 AWG and with less than 2 mm pin-
typed terminals. Only use copper conducting wires with a temperature rating of 60/75°C. The tightening torque
of the PLC terminal screw is 3.8 kgf-cm (3.3 lbf-in).
4.1.7.1 Output Circuits
There are two types of output units. They are relay outputs and transistor outputs.
1. Relay output
The wire diameter specifications are different, since the output wiring of the relay model varies depending on
the type of power supply provided. Only use copper conducting wires with a temperature rating of 60/75°C.
And the tightening torque of the PLC terminal screw is 3.8 kgf-cm (3.3 lbf-in).
