WAGO 750-452 2-Channel 0–20 mA Differential Analog Input Module For WAGO 750 I/O System PLC Current Loops, 12-Bit, DIN-Rail Mount

Ergonomic Analog Input Slice for Precise PLC Signal Acquisition

The WAGO 750-452 Analog Input Module is a compact 2-channel slice for the WAGO 750 I/O System, designed to bring differential current signals from field devices into your PLC with stable, noise-resistant performance and simple DIN-rail integration.

Why It Helps
The 750-452 gives you a clean way to integrate multiple current-driven process signals into your WAGO controller using a single, slim module. Differential inputs and integrated shielding help reduce interference from long cable runs and industrial noise, while clear status and error LEDs simplify diagnostics at the panel. Combined with CAGE CLAMP® wiring, it supports fast installation and reliable long-term operation in control cabinets and marine or industrial environments.

Key Highlights

• Differential current channels for stable measurement
  The module accepts two differential current inputs, providing improved immunity to ground shifts and electrical noise so your PLC receives stable, repeatable signal values from field transmitters. 

• Tight integration with WAGO 750 I/O nodes
  Designed specifically for WAGO 750/753 couplers and controllers, the 750-452 plugs into the internal system bus and is powered via the node’s system voltage, simplifying overall field wiring and cabinet design.

• Clear LED indication for quick troubleshooting
  Separate green function LEDs and red error LEDs per channel help technicians immediately see channel health and overrange conditions directly on the module, reducing downtime during commissioning and maintenance. 

• Compact, DIN-rail mountable form factor
  A narrow housing with CAGE CLAMP® terminals and front-access wiring allows dense packing of I/O in the panel, while still maintaining safe clearances and easy access for service. 

• Engineered for demanding industrial environments
  The module is rated for typical control cabinet temperature ranges, high relative humidity without condensation, and is tested for vibration, shock, and EMC immunity suitable for marine and industrial applications. 

System Compatibility
The WAGO 750-452 Analog Input Module is compatible with the WAGO-I/O-SYSTEM 750/753 and can be used with all standard WAGO fieldbus couplers and controllers except for specified economy variants. It fits into existing WAGO 750 nodes alongside digital I/O, power supply modules, and other analog slices, sharing the internal data bus and system power while transparently exposing its channels in the controller’s process image. 

Applications
Use the WAGO 750-452 in process skids, machinery control panels, marine systems, or distributed I/O racks wherever differential current signals from transmitters need to be brought into a WAGO PLC. Typical uses include monitoring pressure, flow, level, position, or other analog process variables in industrial automation and maritime applications, with the reliability of a CE-marked, IP20-rated module that is approved for a wide range of environments and classification societies.
