Description
Product Overview
The Honeywell CC-TDOB01 is a Series C input/output termination assembly used in Honeywell Experion PKS control systems. Its primary role is to provide the electrical interface between field wiring and the compatible CC-PDOB01 24 VDC digital output module. The assembly supports discrete control applications in which controller commands operate field devices such as solenoid valves, indicator lamps, and interposing relays. Unlike the active output module, the CC-TDOB01 provides the termination and field-connection hardware required to connect output circuits to the plant wiring.
The documented configuration supports 32 digital output points and uses a simplex, nonredundant arrangement. Honeywell’s Series C I/O documentation describes output protection that detects a field short circuit, shuts down the affected point, changes that point’s mode to Manual, and generates an overcurrent soft failure. Other unaffected points can continue operating when their circuits remain healthy. This protection behavior is important during troubleshooting because a fault reported by the control system may originate in field wiring or a connected load rather than in the termination assembly itself.
For replacement work, the Honeywell CC-TDOB01 must be matched to the installed I/O architecture and its associated CC-PDOB01 module. Confirm the complete part number, terminal arrangement, field supply polarity, fuse requirements, and wiring drawings before installation. Honeywell specifically warns that reversing the external supply polarity can damage the digital output module. After replacing the assembly, qualified personnel should check field wiring, verify the 24 VDC supply, inspect the affected output points, and test representative loads before returning the control system to normal operation.
Product Introduction (Non-Templated)
When a discrete output stops operating, the fault may lie in the field load, wiring, output electronics, or termination assembly. The Honeywell CC-TDOB01 provides the Series C termination interface for the CC-PDOB01 24 VDC digital output module, with capacity for 32 output points in the documented configuration.
Check the supply polarity and field wiring before replacing hardware. A reversed external supply can damage the active output module, so commissioning checks must include the electrical connections, not just point status.

Frequently Asked Questions
1. What is the Honeywell CC- used for?
It is a Series C I/O termination assembly for 24 VDC digital outputs. It provides the field wiring interface for the compatible CC- active output module and supports up to 32 output points in the documented configuration.
2. Can I hot-swap the CC- while the control system is running?
Do not assume that live replacement is permitted. The termination assembly connects field wiring and supply circuits, and work on those connections may interrupt outputs or expose personnel to electrical hazards. Follow the applicable Honeywell instructions and site isolation procedures. Confirm whether the intended task involves the termination assembly itself or only the active I/O module.
3. Does the CC- support firmware v3.1?
Firmware v3.1 is not a verified standalone compatibility specification for this termination assembly. The relevant checks are the installed Series C I/O architecture, compatible CC- module, and system configuration. Confirm the actual controller and software release requirements in the applicable Honeywell documentation.
4. Can I use CC- in a redundant output configuration?
CC- is documented as a simplex, nonredundant assembly. Honeywell also documents the CC-TDOB11 for the redundant Series C digital output configuration. A change to redundant hardware requires confirmation of the complete I/O design, module compatibility, wiring, and control-system configuration.
5. What happens if a field output circuit shorts?
Honeywell documentation describes a protection response in which the affected output shuts down, the point changes to Manual mode, and an overcurrent soft failure is generated. The short circuit must be corrected before the point can resume proper output operation. Diagnose the field wiring and connected load before replacing the assembly.
6. How can I verify whether a supplied CC- is genuine and in acceptable condition?
Check the model label and part number, inspect the terminal connections and board condition, and request photographs of the complete assembly. For used or refurbished hardware, obtain written condition disclosure and test records. Confirm that the supplied unit is the termination assembly itself and whether the CC- active module is included separately.
7. What should be checked after installation?
Verify the correct CC- module, terminal assignments, field supply polarity, fuse requirements, and wiring against the approved drawings. Test the affected output points and their connected loads, check for overcurrent faults, and confirm that the controller reports the expected point states before returning the equipment to service.
Procurement recommendation: Specify Honeywell CC-, Series C 24 VDC digital output termination assembly, and confirm compatibility with the installed CC- module. Verify whether the requirement is simplex or redundant, and request clear photographs of the part label and terminal layout. Do not treat the termination assembly and active output module as the same component.
