Item no. 750-538
2-channel relay output; 100 VAC/30 VDC; Potential-free; Relay, 2 changeover contacts

Description

The digital output module switches intrinsically safe circuits of Zone 0+1 (e.g., magnetic valves, contactors, optical/acoustic encoders).

The internal system voltage triggers the relay.

Both maximum switching current and voltage must comply with EN 60079-11.

The switched status of the relays is shown by a LED.

The NO contacts are electrically isolated.

The WAGO-I/O-SYSTEM 750 must be installed either in Zone 2 or in a non-hazardous area.


Note:

The digital output module must only be operated via Ex i 24VDC power supply!

General information (e.g., installation regulations) on explosion protection is available in the WAGO-I/O-SYSTEM 750 manuals!
