This digital input module records binary signals from sensors operating in Zone 0+1 hazardous areas.
NAMUR sensors, optocouplers, mechanical contacts (in conjunction with resistance coupling module, available as an accessory) or other actuating elements can be connected via 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 voltage of 8.2 V.
- Green LED (signal on)
- Red LED (short circuit, wire breakage)
Field and system levels are electrically isolated.
