Description
The Honeywell 51304542-100 is an LCN A cable interface converter board designed for Honeywell TDC 3000 distributed control system architectures. Designated as the KLCN_CA (or KLCN-I/O_CA) module, this card functions as the dedicated physical network transceiver and cable interface for Cable Channel A on the Honeywell Local Control Network (LCN). It mounts into the rear paddleboard card cage of TDC 3000 chassis, directly linking internal node processors to the plant coaxial network infrastructure.
Operating within standard TDC 3000 5-slot, 10-slot, and Dual Node Module files, the 51304542-100 provides signal isolation, impedance matching, and transmission handling for nodes such as the Enhanced PLC Gateway (EPLCG), Universal Station (US), Application Module (AM), History Module (HM), and Network Interface Module (NIM). In dual-redundant LCN environments, the board works in parallel with the 51304544-100 (KLCN_CB) interface card, ensuring isolated communication channels across independent coaxial trunk lines.
Features
- Physical coaxial cable interface dedicated to TDC 3000 Local Control Network (LCN) Cable Channel A.
- Rear paddleboard form factor engineered for TDC 3000 Dual Node, 5-slot, and 10-slot chassis backplanes.
- Designed to work alongside the 51304544-100 (KLCN_CB) card for dual-redundant cable fault tolerance.
- Converts high-speed internal node bus transactions to the 5 Mbps token-passing LCN coaxial standard.
- Provides hardware-level isolation and diagnostic line integrity monitoring for industrial DCS networks.
Applications
- TDC 3000 Local Control Network coaxial Channel A interfacing and transceiver replacement.
- Hardware communications servicing for Honeywell Enhanced PLC Gateways (EPLCG).
- LCN network connection for Universal Stations, History Modules, and Application Modules.
