Overview
Configured for vertical I/O bus interconnection in Honeywell Safety Manager systems, the Honeywell FC-IOBUS-CPIO2 (FS-IOBUS-CPIO2 I/O Bus Interconnection Cable) provides the physical signal path between controller chassis and I/O chassis assemblies. The cable routes I/O bus communication between CPCHAS and IOCHAS hardware.

Process Control and DCS Signal Characteristics
The FC-IOBUS-CPIO2 carries the I/O bus signals between the controller and I/O chassis. Therefore, installation must preserve the intended electrical path and cable routing.
For Honeywell Safety Manager architectures, the cable forms part of the chassis-level communication path rather than a field instrument loop. It does not function as a 4-20 mA HART transmitter interface or a FOUNDATION Fieldbus field device connection.
The supplied information identifies the cable for CPCHAS-to-IOCHAS interconnection and supports redundant or non-redundant system configurations. However, it does not specify conductor count, connector pin assignment, cable impedance, shielding construction, or maximum cable length. These parameters should therefore follow the applicable Honeywell system documentation.
Frequently Asked Questions
Q: Does the FC-IOBUS-CPIO2 directly connect field instruments?
A: No. The supplied data identifies it as a chassis-level I/O bus interconnection cable between CPCHAS and IOCHAS.
Q: Can the cable support redundant I/O configurations?
A: Yes. The supplied specifications identify both redundant and non-redundant controller/I/O configurations.
Q: What is the specified operating temperature?
A: The supplied data specifies -40 deg C to +70 deg C, subject to cabinet ambient conditions.
Field Installation Guidelines
- Install the cable between the designated CPCHAS and IOCHAS connection points.
- Follow the Honeywell chassis installation drawing for connector orientation and termination.
- Keep the cable routing separate from high-current power conductors where practical.
- Avoid sharp bends, excessive mechanical tension, and unnecessary cable loops.
- Maintain the cable shielding and grounding arrangement specified by the system documentation.
- Verify connector engagement before system energization.
- Do not alter connector wiring or pin assignments without an approved Honeywell wiring specification.
- For redundant architectures, route and terminate each bus connection according to the specified redundancy arrangement.
- After installation, verify physical continuity and inspect the complete communication path before commissioning.
