WAGO 750-485 2-channel analog input; 4 … 20 mA; Single-ended; Intrinsically safe, Automation Technology, I/O Systems.

This analog input module supplies intrinsically safe signal conditioners in hazardous areas classified as Zone 0 and Zone 1, and processes their analog measurement signals.

The WAGO I/O System 750/753 must be installed either in Zone 2 or in a non-hazardous area.

The 24 V supply voltage is fed in via the power jumper contacts.

The transmitter power supply is conditionally short-circuit protected.

The shield connection directly connects to the DIN-rail.

Indicators:

Green LED (signal current on/off)

Red LED (wire breakage, measurement range overflow/underflow)

Field and system levels are electrically isolated.
