Honeywell CC-TDlL01 digital input module
The Honeywell CC-TDIL01 (part number 51308386-175) is a 32-channel 24V DC isolated digital input IOTA module for the Experion PKS C300 system C series. It is responsible for acquiring 24V DC digital signals from field switches, limit switches, status contacts, etc., and uploading them to the controller. It supports channel grouping and isolation, disconnection diagnosis, and redundant deployment. It is a core I/O component for equipment status monitoring, safety interlocking, and fault early warning in industrial scenarios such as petrochemical and power industries.

Core Functions
32-Channel High-Density Digital Acquisition: Parallel acquisition of 32 channels of 24V DC digital signals, compatible with field switches, limit switches, safety contacts, etc., providing the controller with status data such as equipment start/stop, valve position, and interlock triggering.
Grouped Electrical Isolation: 4 groups × 8 channels of grouped isolation design reduce inter-group signal crosstalk and ground potential difference effects, improving signal reliability in complex electromagnetic environments.
Comprehensive Diagnosis and Disconnection Detection: Real-time monitoring of channel disconnections, overvoltage/undervoltage, and module faults, with early warnings via the DCS system. Disconnected channels are marked as "invalid" to prevent erroneous control actions.
Redundancy and High Availability: Seamless fault switching during redundant deployment; hot-swappable design supports online replacement, ensuring continuous operation of critical interlocking circuits.
Industrial Adaptability and Safety: Stable operation over a wide temperature range; explosion-proof design suitable for hazardous areas; surge/overcurrent protection; meets SIL2 signal integrity requirements.
