Honeywell 51403519-160

The Honeywell 51403165-400 is an Operator Keyboard Assembly for Honeywell TDC 3000 / TDC 2000 operator consoles, specifically the Z-station . It uses a proprietary Honeywell interface rather than standard USB or PS/2 connections.

The Honeywell K4LCN-16 51403519-160 is a high-capacity LCN Memory Processor Module designed for the TDC 3000/TPS distributed control system. It serves as a critical node on the Local Control Network (LCN), executing control logic, managing system memory, and handling high-speed network communications. Featuring 16 megawords of onboard memory and a Motorola 68040 processor, it addresses the memory limitations of older K4LCN-8 variants, preventing data loss during high alarm throughput conditions.
