The Honeywell CC-TDI230 operates as a high-reliability Digital Input Termination Assembly (IOTA) within the Experion PKS Series C architecture. This module specializes in detecting discrete signals from 220/240 VAC field devices, such as industrial limit switches and power status contacts. It supports redundant configurations, providing a fault-tolerant interface that ensures continuous process monitoring even if a single component fails. This unit is supplied as 100% brand new and original factory hardware.

High-Voltage Signal Directness: The CC-TDI230 accepts 240 VAC inputs directly from field devices, eliminating the need for external interposing relays and simplifying cabinet wiring and design.
Fault-Tolerant Architecture: Supports redundant module pairing, allowing a secondary module to maintain signal acquisition if the primary module fails, ensuring uninterrupted monitoring.
Wide Voltage Tolerance: Operates reliably across 180–264 VAC, accommodating fluctuations in industrial power systems and preventing false alarms during voltage instability.
Rapid Signal Response: With a maximum input delay of 25 ms, the module delivers fast and accurate discrete signal updates suitable for safety interlocks and sequence-of-events (SOE) applications.
Yes, although the CC-TDI230 supports redundancy, it can also be configured for simplex operation depending on system design and Experion PKS channel requirements.
The module uses defined sense current thresholds. Signals below 0.32 mA are interpreted as OFF, while currents above 1.11 mA are recognized as ON, effectively filtering out leakage currents and electrical noise.
The pick-up threshold ensures that the input is only registered as ON when sufficient voltage is present to reliably drive the field device, improving accuracy and preventing false state detection.
