This digital input module records binary signals from sensors operating in Zone 0+1 hazardous areas, permitting channel-by-channel short circuit and wire-break diagnostics. NAMUR sensors, optocouplers, mechanical contacts (LED diagnostics can be turned off via control byte) or other actuating elements can be connected via intrinsically safe devices.
The WAGO-I/O-SYSTEM 750 XTR 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)
- Red flashing LED (wire-break)
Field and system levels are electrically isolated.
The device is ideal for operation in harsh environments thanks to:
- Extended temperature range
- Greater immunity to impulse voltages and electromagnetic interference
- Higher vibration and shock resistance
The digital input module must only be operated via 24 VDC Ex i XTR power supply (750-606/040-000)!
General information (e.g., installation regulations) on explosion protection is available in the WAGO-I/O-SYSTEM 750 XTR manuals!
