Wago 750-481/003-000 fieldbus module

2-ch analog in,Resistance measurement, Intrinsically safe The analog input module allows the direct connection of Pt or Ni resistance sensors and potentiometers located in hazardous environments of Zones 0 and 1.

The WAGO-I/O-SYSTEM 750 must be installed either in Zone 2 or in a non-hazardous area. The 24V supply is derived from the module's power jumper contacts.

The shield (screen) is directly connected to the DIN rail.

LED indicators:

- Green LED (availability ON/OFF)
- Red LED ( short circuit, wire breakage, measuring range overflow/underflow)

Field and system levels are electrically isolated.

<b>Hinweis</b>:

Note: The analog 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!

<b>Voltage via power jumper contacts</b>: 24 VDC (provided via Ex i supply UO = max. 27.3 V)
