Model: FSāIOBUSāCPIO
Brand: Honeywell
Series: FS / IOBUS (I/O Bus)
Type: I/O Bus Control Chassis / Bus Interface
Product Description:
The FSāIOBUSāCPIO is an I/O bus interface chassis module used in Honeywellās TotalPlant Solution (TPS) and DCS (Distributed Control System) architectures. It functions as the high-speed link between the controller chassis and the I/O chassis, relaying data, scans, updates, and diagnostics. The module ensures reliable communication in safety or process control systems, providing a backbone for modular I/O distribution.
It is typically rack-mountable and supports integration into redundant or non-redundant bus topologies. The chassis is designed for industrial use ā robust against electrical and environmental stressors.
