Honeywell FC-IOBUS-CPIO I/O Bus Expansion Module

Central Communication Link for Safety Manager Systems

The Honeywell FC-IOBUS-CPIO establishes a vertical I/O bus between the controller chassis and one or more I/O chassis . This module facilitates essential scan, test, and update actions between the QPP module and connected I/O units . Furthermore, the FC-IOBUS-CPIO supports both redundant and non-redundant configurations for flexible system integration . Its compact form factor also enables easy installation within standard control cabinets.

Hardware Specifications

System Compatibility and Integration

The Honeywell seamlessly connects to Honeywell Safety Manager and Experion PKS platforms . This module uses a 34-wire flat cable design optimized for vertical cabinet routing, which minimizes space usage and maintains signal integrity . It also provides separate IO bus1.x and IO bus2.x connections, ensuring proper pairing for redundant I/O bus architectures . For non-redundant setups, engineers must terminate each bus using a TERM-0001 terminator .

Installation and Operational Guidelines

This lightweight assembly weighs only 0.31 kg, making handling and mounting straightforward . The FC-IOBUS-CPIO carries UL and CSA approvals for use in certified safety applications . For cabinet-to-cabinet connectivity, extension systems require related models such as FS-IOBUS-CPX-x and FS-IOBUS-CPIOX . Consequently, engineers can build scalable safety instrumented systems with deterministic performance across distributed I/O racks.
