Foxboro FBM2/36 P0500RG I/O Termination Cable Assembly

Product Description

The FBM2/36 P0500RG is a dedicated interface cable assembly used in Foxboro I/A Series systems for connecting FBM2/36 input/output modules to the system I/O bus. It is engineered to maintain signal integrity between distributed control hardware and field-level termination points.

The assembly combines a DB9 system-side connector with a screw-terminal field interface, allowing structured wiring transitions between cabinet backplanes and external instrumentation. Its design emphasizes electrical stability, EMI reduction, and mechanical resilience for long-term deployment in continuous process operations.

Manufacturing variants may differ slightly in length, shielding, and environmental sealing, but all configurations are intended for stable industrial signal routing under demanding conditions.
