Foxboro RH101AB I/O module

Product Description

Model: Foxboro RH101AB, Brand Foxboro (owned by Schneider Electric), I/A Series DCS Termination Assembly (TA). It works with FBM fieldbus I/O modules. This terminal unit receives field instrument signals and performs signal distribution & conversion. Mounted directly on FBM baseplate, it transmits 4-20mA analog and discrete signals from field instruments to I/O modules. It adopts spring-cage terminals for convenient wiring and supports HART communication with circuit open/short detection. It is an essential wiring component inside Foxboro I/A DCS control cabinets, widely used for spare parts replacement of legacy DCS projects.
