Honeywell TK-CCR014 Redundant Net Interface Module

Configured for redundant control network communications in Honeywell TDC 3000 / Process Manager systems, the Honeywell TK-CCR014 (TK-CCR014 Cage Card Interface) provides direct physical/electrical execution. Operating on a nominal supply of 24 VDC, this specialized PC board PLC add-on module handles dual-channel network interface routing across fault-tolerant rack backplanes. The assembly delivers seamless physical media access and hardware-level switching between primary and secondary network nodes, preventing communication disruptions during single-point cable or interface failures without requiring high-level processor intervention.

Hardware Specifications

Process Control & Channel-to-Channel Isolation Characteristics

The TK-CCR014 incorporates high-density channel-to-channel isolation circuits designed to suppress common-mode electrical noise and prevent ground loops across distributed control network segments. Interfacing with transmitter networks and DCS nodes, the module supports stable analog and digital data exchange standards. Integrated cold junction compensation (CJC) logic and calibrated galvanic isolation barriers shield high-speed signal pathways from field surges, maintaining network synchronization under harsh industrial plant operating conditions.

Frequently Asked Questions

Q: Can the TK-CCR014 module be hot-swapped during active system operation? A: Yes, the TK-CCR014 supports live rack insertion and removal provided the system card cage backplane ground connection remains unbroken and proper ESD precautions are observed.

Q: What is the primary function of the 24 VDC input connection on the card? A: The 24 VDC supply powers the on-board network interface logic, optical coupler arrays, and redundant switching relays dedicated to dual-bus communication fallback.

Q: How does the module execute failover between redundant communication paths? A: Hardware-level carrier detection and physical layer monitoring instantly trigger channel switching upon loss of signal integrity or link activity on the primary bus.

Field Installation Guidelines

• Electrostatic Discharge (ESD) Protection: Wear a grounded anti-static wrist strap when handling the raw PC board assembly to avoid damaging sensitive CMOS components.
• Card Cage Alignment: Insert the card firmly into the designated cage slot, ensuring card-edge connectors engage evenly with the backplane pin assembly.
• Cable Shielding & Grounding: Terminate overall network cable shields directly to the chassis ground bar using low-impedance grounding clamps; maintain a continuous shield path.
• Power Supply Validation: Verify that the incoming 24 VDC bus voltage remains within standard tolerance limits (+/- 10%) prior to seating the module under powered conditions.
• Wiring Routing Constraints: Maintain a minimum clearance of 200 mm between communication lines connected to the card cage and high-voltage AC power wiring.
