earth them.
Terminal SD is a common terminal for 24V external power supply terminal (+24). The open collector circuit is isolated from the
internal control circuit by photocoupler.
Terminal SE is a common terminal for the open collector output terminal (Y0). The contact input circuit is isolated from the
internal control circuit by photocoupler.
(4) Wiring instructions
1) It is recommended to use the cables of 0.3mm
2) The maximum wiring length should be 30m.
3) Do not short across terminals +24 and SD. It may cause a failure to the external power supply.
4) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power
