Wago 750-624/020-001 Field Supply Filter, 24 Vdc Hi

Why Choose the WAGO 750-624/020-001 Field-Side Power Supply Filter Module?

The WAGO 750-624/020-001 is a high-isolation field-side power supply filter module designed for the WAGO I/O System 750 and 753. It protects the 24 V DC field supply against surge voltages and electrical disturbances, helping maintain stable power and reliable operation of distributed PLC and fieldbus automation systems.

Industrial automation environments often include inductive loads, switching devices and motor drives that introduce high-energy disturbances into DC power networks. The 750-624/020-001 integrates transient suppression and surge filtering to reduce these disturbances and protect sensitive control electronics within modular automation nodes. :contentReference

This variant features higher electrical isolation and operates without power jumper contacts, making it suitable for applications requiring supply isolation or insulation monitoring. It is commonly used in demanding sectors such as marine, offshore and hazardous-area automation systems. :contentReference

Industrial Automation Power Protection

Modern industrial control systems operate in environments where switching inductive loads and electrical equipment can introduce voltage transients onto DC power lines. These disturbances can disrupt communication or damage sensitive electronics.

The WAGO 750-624/020-001 protects distributed I/O systems by filtering high-energy disturbances and suppressing surge voltages on the 24 V field supply. This ensures stable operation of PLC nodes and automation networks even in harsh industrial or marine environments. :contentReference

Typical Applications
