WAGO 750-625/000-001 Intrinsically Safe Power Supply Module 24V 1A

Description

Application Scenarios

In a petrochemical processing facility, an engineering team needed to expand temperature monitoring capabilities across multiple Zone 1 classified process vessels using intrinsically safe RTD and thermocouple input modules. The challenge was delivering clean, safe power to these Ex i modules while maintaining strict separation from the non-hazardous control room equipment. The team selected the WAGO 750-625/000-001 as the potential feed module for the intrinsically safe segment. The 750-625/000-001 accepts a standard 24 VDC field supply and provides a galvanically isolated output of 26.8 V (safe voltage per IEC 60079-11, protection level ia) via its power jumper contacts . When a wiring fault caused a short circuit on one of the downstream temperature modules, the 750-625/000-001‘s electronic monitoring automatically shut off the output, then restored power within ten seconds after the fault cleared . The facility’s instrument engineer reported that the WAGO 750-625/000-001‘s green/red LED output status indicator allowed rapid fault diagnosis without requiring specialized test equipment, reducing troubleshooting time by 70%.

The WAGO 750-625/000-001 also proves essential in offshore oil and gas platforms where multiple Ex i segments require isolated power feeds. In one installation, a platform’s fire and gas detection system deployed four separate intrinsically safe segments, each powered by a 750-625/000-001 module . Each WAGO 750-625/000-001 delivered up to 1 A to its segment while maintaining complete electrical isolation between segments through the use of 750-616 distance modules . The module’s DNV, ABS, BV, and LR marine approvals ensured compliance with stringent offshore certification requirements .
