Product Overview

The RH101AY is a hazardous-rated field termination block for Foxboro I/A Series and Foxboro Evo DCS, matched exclusively to the FBM247 universal configurable I/O module. It supports 8 software-definable channels, each switchable between 4–20 mA AI, AO, DI, pulse input, with native HART support for smart instruments. This variant is built for Class I Div.2 / Zone 2 non-incendive environments, fitted with compression screw terminals, per-channel fuse protection and HART access jacks for field calibration. It mounts directly to the I/O rack carrier, eliminates intermediate D‑Sub cabling, and allows hot-swap of the FBM247 card without breaking adjacent control loops. It is widely stocked for offshore platforms, refineries and petrochemical process loops.
