4-9. External I/O signal (control connector)
I/O circuits and internal circuits are electrically insulated by photo-coupler.
An external DC24V (power source for the external I/O signal circuit) must be prepared separately.
4-9-1.Connector pin assignments
Compatible connector: 57-30240 manufactured by DKK
* COM [1, 12, 13, 24 pin] is internally connected for sink type.
* COM [1, 13 pin] is internall
y connected as +24V and [12, 24 pin] as +24V_RTN respectively for
source type.
