Wago 750-438 WAGO I/O-SYSTEM 750 Intrinsically safe Digital Input Module
2-Channel Digital Input NAMUR Proximity switch, Intrinsically safe, Sensor supply voltage: DC 8,2 V, short-circuit-protected, isolated channels, Sensor connection: 2x (2-conductor), Input characteristic: high-side switching, Input filter: 3 ms
The digital input module receives the binary signals from sensors operating in hazardous environments of Zones 0 and 1. NAMUR sensors, optocouplers, mechanical contacts or other actuating elements can be connected by means of approved intrinsically safe devices.
The WAGO-I/O-SYSTEM 750 must be installed either in Zone 2 or in a non-hazardous area. Each sensor is supplied with a short-circuit-protected 8.2V supply.
LED indicator: Green LED (signal on)
Field and system levels are electrically isolated.
Note: The digital input 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!
24 VDC (provided via Ex i supply UO = max. 27.3 V)
