Model: FS‑IOBUS‑CPX‑1
Brand: Honeywell
Series / Family: FS / IOBUS / CPX series
Type: I/O Bus Cable / Interface Module
The FS‑IOBUS‑CPX‑1 is a communication cable or interface module used to connect a controller cabinet (CPCHAS) to an external I/O cabinet (IOCHAS) in distributed control systems (DCS). It supports reliable data transfer, signaling, and synchronization between these chassis over the system’s I/O bus infrastructure.
It is designed to operate in industrial environments, offering robust connectivity across moderate distance with shielding, correct voltage handling, and environmental resilience.
