■DCS STATUS OUTPUT: dry contact or open collector

Contact detecting: 24V DC, approx. 20mA

OUTPUT

■ELECTROMAGNETIC VALVE: voltage contact

Rated load: 120V AC @0.5A (cosø=1)

24V DC @0.5A (resistive load)

Load current: 8A max. for the total of 16 channels

24V DC @3A (resistive load)

Relay protection: For maximum relay life with

inductive loads (e.g. coil), external

protection including noise quenching is

recommended.
