Product Details And Specifications

Compressor Controls Corp TIOC-555HD Transition Module – Obsolete CCC Spare Part

DriveKNMS maintains verified inventory of the TIOC-555HD for facilities that require a direct hardware replacement without system redesign. This is not a workaround. It is a documented, tested spare that allows continued operation of the existing CCC control architecture.

Technical Specifications

Note: Electrical parameters not independently verified. Specifications are based on known CCC module family characteristics. Buyers are advised to cross-reference against original CCC documentation prior to installation.

Solving the Discontinued Hardware Crisis

Compressor Controls Corp has been a dominant supplier of turbomachinery protection and control systems across refineries, LNG terminals, offshore platforms, and power generation facilities since the 1970s. The CCC architecture — including the TIOC-series transition modules — was engineered for long-cycle industrial deployment. Many of these systems remain in active service 20–30 years after initial commissioning.

The TIOC-555HD functions as a signal transition interface within the CCC control cabinet, routing I/O signals between field instruments and the core control processor. Its failure disrupts the signal chain at a structural level. Unlike a failed sensor or transmitter, a failed transition module cannot be bypassed through field wiring changes alone. The control system loses visibility of the connected process variables.

For plant managers facing this situation, the options are: source a verified replacement module, or initiate a full control system replacement. The latter path involves months of engineering work, FAT/SAT testing, and a planned shutdown window. For facilities operating under continuous production mandates, that path is not viable on short notice. A verified spare TIOC-555HD eliminates that decision entirely.

Extending Asset Life by 5–10 Years: A Practical Framework

Facilities that proactively manage legacy CCC hardware can defer system migration by a decade or more. The following approach is used by maintenance teams in refineries and gas processing plants operating CCC systems past their nominal end-of-support date:

Condition & Reliability Assurance

All obsolete and legacy modules sourced through DriveKNMS undergo a structured 5-step quality process before dispatch:

Key Features for System Maintenance

• Drop-in replacement: The TIOC-555HD installs directly into the existing CCC cabinet slot. No backplane modification is required.
• No reprogramming required: Configuration is held in the CCC control processor, not in the transition module. Replacement does not require re-engineering of control logic.
• No system redesign cost: Replacing this module avoids the engineering cost associated with migrating to a new I/O platform. The existing field wiring, cabinet, and processor remain in service.
• Immediate operational restoration: A verified spare on-site reduces mean time to repair (MTTR) from weeks to hours.
• Documented traceability: Each unit shipped includes condition documentation suitable for inclusion in plant maintenance management systems (CMMS).

Q: How many spares should we hold for a CCC system?
A: For non-redundant modules on critical compressor trains, the standard recommendation is a minimum of one installed spare per module type, with a second unit in off-site storage. For facilities with multiple identical CCC systems, a shared spare pool managed by a specialist supplier is a cost-effective alternative to holding individual site stocks.
