The ABB Bailey IPFLD125 is a Field Power Module designed for the INFI 90 distributed control system (DCS). It provides regulated 125 V DC field power to support industrial instrumentation, control devices, and automation subsystems.
In large-scale process industries, stable field power distribution is essential for maintaining consistent operation of sensors, actuators, and control loops. The IPFLD125 is engineered for high-reliability environments such as power plants, oil & gas facilities, and petrochemical processing units, where uninterrupted field power directly impacts system safety and performance.
It is widely recognized as a core power distribution component within ABB Bailey legacy automation architectures.
