Honeywell CC-TDOB01 51308371-175 C300 Digital Output Module

Product Overview

Honeywell CC-TDOB01 51308371-175 C300 Digital Output Module: Seamless Replacement & Upgrade Solution

The Honeywell CC-TDOB01 (part number 51308371-175) is a 24 VDC Digital Output Module designed for the Honeywell C300 Controller platform within the Experion PKS distributed control system architecture. As legacy DCS installations age and original spare parts become increasingly difficult to source, the CC-TDOB01 remains a critical component for facilities running C300-based control loops across oil & gas, refining, chemical processing, power generation, and pulp & paper industries. TOPNLMS maintains verified stock of this module to support both emergency replacement and planned migration projects, with same-week dispatch from Xiamen and a 12-month warranty on every unit.

Whether your plant is executing a like-for-like swap of a failed module, consolidating spare parts inventory ahead of a scheduled turnaround, or executing a phased migration from an older TDC 3000 or PlantScape system to a modern Experion PKS C300 architecture, the CC-TDOB01 fits directly into the existing C300 I/O Link infrastructure without requiring changes to controller configuration, FTA wiring, or SCADA tag mapping.

Seamless Upgrade Solutions

A successful CC-TDOB01 replacement or migration project rarely involves a single module in isolation. In practice, field engineers working on C300 I/O upgrades will simultaneously address the broader system context to ensure continuity of control and minimize plant downtime.

On the field termination side, the CC-TDOB01 pairs with the CC-TAID01 or CC-TAIX01 Field Termination Assembly, which provides the screw-terminal interface between the module and field wiring. When migrating from a TDC 3000 HPM installation, existing field cables can often be re-terminated directly onto the C300 FTA without re-pulling wire, provided signal levels and loop power configurations are verified. The CC-PAIH02 power adapter is commonly required when integrating the FTA into existing marshalling cabinets that were originally wired for HPM-style termination blocks.

For installations requiring digital input capability alongside the CC-TDOB01 output channels, the CC-TDIL01 (51308369-175) Digital Input Module occupies the same CIOM-A chassis slot format and is configured through the same Experion Control Builder environment, simplifying mixed I/O cabinet layouts. In redundant configurations, a second CC-TDOB01 module is installed in the adjacent chassis slot, with the redundancy pair managed automatically by the C300 Controller (CC-PCF901) without requiring manual switchover logic in the control strategy.

Communication integrity across the I/O Link is maintained by the CC-LINK01 I/O Link Interface module, which connects the CIOM-A chassis to the C300 controller cabinet. In larger installations with multiple CIOM-A chassis distributed across the control room or field junction boxes, the CC-LINK02 extended I/O Link module supports longer cable runs without signal degradation. Where Modbus RTU or PROFIBUS DP legacy devices remain in service alongside the C300 system, the CC-PDOB01 PROFIBUS DP Output Module or a dedicated Honeywell HC900 Hybrid Controller gateway can bridge protocol differences without requiring a full rip-and-replace of field instrumentation.

For plants upgrading operator interface alongside the I/O migration, the Experion PKS Station (ESVT) or a compatible Honeywell HMIWeb Display Builder workstation provides the supervisory layer that maps directly to the CC-TDOB01 channel tags configured in Control Builder, ensuring that alarm rationalization and display graphics require only tag renaming rather than full recreation. Power distribution within the control cabinet is typically handled by a Honeywell 24 VDC DIN Rail Power Supply (PS-24VDC) sized to the total CIOM-A chassis load, and signal isolation between legacy 4–20 mA loops and the new digital output channels can be achieved using Phoenix Contact or Pepperl+Fuchs signal isolators where loop power configurations differ between old and new termination schemes.

Retrofit Guidance FAQ

Q: Can the CC-TDOB01 replace a TDC 3000 HPM Digital Output module directly?
A: Not as a direct plug-in replacement. The TDC 3000 HPM uses a different card cage, backplane bus (UCN/FTA), and physical form factor. A migration from TDC 3000 to C300 requires installing a new CIOM-A chassis, re-terminating field wiring to C300-compatible FTAs (such as the CC-TAID01), and rebuilding the control strategy in Experion Control Builder. However, field wiring from the marshalling cabinet to the process can typically be reused, significantly reducing installation cost and downtime.

Q: Is the CC-TDOB01 backward compatible with earlier Experion PKS releases?
A: The CC-TDOB01 (51308371-175) is qualified for Experion PKS R400 and later. For sites running R300 or earlier, a firmware compatibility check is recommended before installation. TOPNLMS can provide the module datasheet and release notes upon request to support your site’s compatibility assessment.

Q: Does replacing the CC-TDOB01 require a controller download or process restart?
A: In a redundant C300 configuration, the failed module can be replaced online using the hot-swap capability of the CIOM-A chassis. The redundant module continues to drive field outputs while the replacement is seated and synchronized. In non-redundant configurations, a brief output interruption is expected during module swap; coordination with operations to place affected loops in manual mode prior to replacement is standard practice.

Q: What wiring changes are needed when migrating from a legacy DO module?
A: Field wiring termination points differ between TDC 3000 FTAs and C300 FTAs. The CC-TAID01 FTA uses a standard screw-terminal block layout that is documented in Honeywell’s PM09-410 installation guide. In most cases, existing field cables can be landed directly on the new FTA terminals after verifying wire gauge, shield grounding, and loop power polarity. No changes to the field device side (solenoid valves, motor starters, relay coils) are required.

Q: Can the CC-TDOB01 communicate over PROFIBUS or Modbus?
A: The CC-TDOB01 communicates exclusively over the Honeywell C300 I/O Link (CIOM-A proprietary bus). It does not natively support PROFIBUS DP or Modbus RTU. For integration with legacy PROFIBUS or Modbus field devices, a separate protocol gateway module (such as the CC-PDOB01 or a third-party Modbus-to-I/O Link bridge) is required within the Experion PKS architecture.

Q: What physical space is required in the control cabinet?
A: The CC-TDOB01 occupies one slot in a standard Honeywell CIOM-A I/O chassis. The CIOM-A chassis is available in 4-slot and 8-slot configurations and mounts on a standard 35 mm DIN rail. The associated CC-TAID01 FTA mounts separately on a DIN rail in the marshalling section of the cabinet. Total cabinet space requirements are significantly less than equivalent TDC 3000 HPM card cage installations, often enabling consolidation of multiple HPM cabinets into a single C300 control cabinet.
