By factory default, the input logic of the multi-function input terminal circuit is set to the sink logic.

Note 1: When connecting a relay to the multi-function output terminal, install a surge-absorbing diode in parallel with the relay. The output circuit can break down due to surge voltage when the relay is switched on/off. Note 2: For the signal line, use a twisted shield wire and apply the shield coating as illustrated on the next page. Keep the length to 20 m or less. 2-13 SC S6 S5 S4 S3 S2 S1 PSC FV FI P1 Y R
