Wago-750-484/000-001
2-channel analog input

2-channel analog input; 4 … 20 mA HART; NAMUR NE 43; Intrinsically safe; blue


The analog input module connects two field-side transformers equipped with a HART interface to be used in hazardous environments Zone 0 + 1.

It powers transducers, reads process values via the analog interface, and provides HART communication to configure and import dynamic variables.

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

The 24V supply is taken from the power bridge contacts via multiplexers to the field contacts (HART +). The shield (screen) is attached directly to the DIN rail.

Measurement input, current max. It is equipped with a current limiter that limits it to 25 mA. These modules can supply voltage to 2-wire transducers that do not have a dedicated power supply.

Up to 4 HART dynamic variables (PV, SV, TV, QV) per channel can be mapped in the cyclic process image. The HART protocol for HART communication with connected smart HART field devices can be mapped (set) in the cyclic process image of the coupler or controller.

FDT/DTM device drivers are available for certain (programmable) couplers and provide HART tool routing to the connected HART device.

Note: The analog input module must only be operated via the Ex i 24VDC power supply!

General information on explosion protection (e.g. mounting regulations) is available in the WAGO-I/O-SYSTEM 750 manuals!
