Filter modules serve marine applications

WAGO 750-624/020-002 and 750-626/020-002 filter modules have been upgraded to include built-in ground fault diagnostics. Modules are able to monitor both the +24Vdc and 0Vdc supply connections for impedance to ground. Suitable for marine applications, engineers can design in a ground fault test device to detect error resistance to Earth. The built-in ground fault detection means there is no need for an external device for ground fault detection after a 24Vdc power supply. Multi-purpose modules help reduce system costs and commissioning time.
