A housing is required when using the CN2 terminal on the back side of the digital operator.
1m analog input cable (code no. 3G3MV-PCN-CN2) is available for housing on request
A +24 V power supply is required for sequence connection by PNP transistor (+24 V common) .
Shows the following two kinds of connections (factory setting) :
· Input signals (S1 to S7) are non-voltage contacts
· Sequence connection by NPN transistor (0V common)
