The Honeywell CC-TDI110, also cataloged as the CC-TDI110 Digital Input Module Termination Assembly, operates as a dedicated hardware component for discrete signal acquisition within Experion Series C DCS platforms. It provides structured physical termination and signal routing for discrete field contacts, switches, and digital sensors interfacing with Series C digital input modules.

Channel Isolation and Dynamic Signal Conditioning
The Honeywell CC-TDI110 features channel-to-channel isolation architecture engineered to mitigate common-mode noise and protect backplane logic from field-side voltage transients. Built-in filter circuitry suppresses contact bounce from mechanical field switches and prevents electrical interference from coupling into adjacent 4-20 mA HART loop protocol lines. This ensures deterministic discrete status transfer across the Experion PKS system architecture.
Frequently Asked Questions
Q: How does the CC-TDI110 termination assembly protect upstream control electronics from field faults?
A: Integrated channel-to-channel isolation barriers and surge suppression circuits isolate high-voltage spikes and ground loops originating on field contact lines from propagating to the backplane.
Q: What field conductor gauges are supported on the CC-TDI110 terminal blocks?
A: Standard screw compression terminals accept field wiring sizes up to 14 AWG. Conductors should be properly torqued and stripped to prevent exposed copper strands.
Field Installation Guidelines
Secure the CC-TDI110 assembly onto the designated carrier chassis channel within the enclosure.
Bond the protective ground lug to the cabinet protective earth (PE) bus using a low-impedance copper grounding strap.
Dress field contact wiring into the screw compression terminal blocks, enforcing a minimum 50 mm clearance from high-voltage AC cables.
Verify all field cable shields are tied to the central shield bar at a single grounding point to prevent circulating ground currents.
Seat the corresponding digital input card into the assembly interface headers until retaining latches fully lock into position.
