Why Choose the WAGO 750-624 Field Supply Filter?
The WAGO 750-624 is a compact 24 V DC field-side power supply filter with surge protection designed for the WAGO I/O System 750/753. It protects the field supply against transient overvoltages and high-energy disturbances on DC supply lines, helping maintain reliable operation of sensitive industrial automation equipment.
Designed for demanding automation installations, the 750-624 helps suppress disturbances caused by switching overvoltages and inductive loads. Its integrated transient protection makes it particularly useful where clean and dependable 24 V DC field power is required, including applications using safety-related I/O and installations subject to stringent power quality requirements.
The module operates with a 24 V DC field supply with a tolerance of -25% to +30% and provides a 10 A current-carrying capacity through its power jumper contacts. Three incoming and three outgoing power jumper contacts allow the filtered field supply to be distributed through compatible downstream modules within the I/O station.

Surge-Protected Field Power for Industrial Automation
Industrial DC supply networks can experience transient overvoltages generated by switching operations and inductive loads. These disturbances can affect sensitive sensors, actuators and I/O electronics. The WAGO 750-624 filters the 24 V DC field supply and provides transient protection to help prevent high-energy disturbances from reaching connected field circuits.
The module integrates directly into the WAGO I/O System 750/753 and distributes the protected field supply through its power jumper contacts. This makes it suitable for automation architectures where dependable field power, surge suppression and compact modular installation are important requirements.
