Product Overview

The Honeywell CC-TDI230 is a high-density discrete signal processor engineered for the Experion Process Knowledge System (PKS) Series C architecture. Functioning as a 32-channel interface, this module is specifically optimized for high-voltage sensing, providing the C300 controller with real-time status updates from a vast array of on/off field devices. Its versatile input circuitry is designed to accommodate multiple industrial voltage standards, ranging from 120V AC/DC up to 240V AC. By consolidating 32 discrete points into a single, compact module, the CC-TDI230 significantly reduces the footprint required for high-voltage monitoring in Series C cabinets while maintaining the high availability and rugged performance standards essential for mission-critical Distributed Control System (DCS) operations.

Industrial Deployment and Automation Utility

In Heavy Power Distribution and Switchgear Monitoring, the CC-TDI230 provides the necessary high-voltage interface to track the status of large circuit breakers and auxiliary contacts. The 1500V galvanic isolation is a critical safeguard in these environments, preventing high-energy transients or ground loops from migrating into the sensitive Series C backplane and protecting the logic solver from catastrophic electrical failure. The ability to sense 125V DC battery systems alongside 240V AC utility power makes it a highly flexible solution for utility-scale automation.

Within Chemical Processing and Hydrocarbon Storage, this module serves as the primary status monitor for valve limit switches and motor run-contacts across extensive tank farms. The 32-channel high-density design allows for the consolidation of field signals into a single cabinet bay, reducing the amount of space required for remote instrument enclosures (RIEs). Maintenance teams benefit from the clear separation between field-side voltage and system-side logic, which simplifies the diagnostic process during routine system audits and troubleshooting of discrete loops.

For Large-Scale HVAC and Building Automation Systems, the CC-TDI230 facilitates the monitoring of line-voltage thermostats and industrial relays. Its compatibility with 240V AC signals allows it to interface directly with common utility voltages without the need for interposing relays or additional signal conditioning hardware. This direct-to-DCS connectivity streamlines the system architecture, reduces points of failure, and ensures that critical environmental control parameters are reported to the Experion platform with maximum accuracy and reliability.
