This SHEV control uses a 24 VDC pulse output to control electromagnets/electrovalves (CA/CFR) or pneumatic valves with electric components (EA/EZ). The impulse control IS 3b enables the setting up of one SHE group and has two signal lines. It delivers a total output current of up to 4 A.
Two potential-free contacts are available for forwarding fault or alarm messages. One of the contacts can be wired to the internal 24 VDC output for controlling external warning devices.
