Honeywell FC-IOBUS-CPIO Vertical I/O Bus CPCHAS to IOCHAS

The Honeywell FC-IOBUS-CPIO is a vertical I/O bus consisting of a 34-wire flat cable. It provides the communication link between the Controller chassis (CPCHAS-0001 / 0002 / 0003) and one or more I/O chassis (IOCHAS-0001S/R, 0002S/R, 0003S/R) in Safety Manager systems.

Core Specs

FAQ

• What does it connect? Controller chassis (CPCHAS) to I/O chassis (IOCHAS).


• Cable construction? 34-wire flat cable with 34-pole latch connectors.


• Redundancy supported? Yes, works in both redundant and non-redundant systems.

Installation Guide

1. Identify the IO bus connector on the Controller chassis backplane (marked IO busx.x).


2. Connect one end of the FC-IOBUS-CPIO to the Controller chassis.


3. Route the flat cable to the I/O chassis and connect to the corresponding IO bus connector on the IOB backplane.


4. Secure both 34-pole latch connectors firmly.


5. Power up the system and verify I/O communication status.

Selection Tips

• Required whenever a Safety Manager system uses separate Controller and I/O chassis.


• Confirm exact chassis models (CPCHAS and IOCHAS series) for compatibility.


• Use genuine Honeywell cable to maintain signal integrity and system diagnostics.
