Honeywell 51403299-200 Local Control Network Processor for Process Automation

The 51403299-200 local control network processor manages communication traffic across Honeywell control networks. This module coordinates data exchange between controllers and operator stations. Plant engineers rely on its deterministic handling of network tasks in continuous processes.

Physical Dimensions and Weight

The 51403299-200 occupies 2 slots in a standard Honeywell card cage. Its faceplate measures 40 mm in width and 178 mm in height. The module weighs approximately 0.5 kg, so card cage loading stays balanced during expansion.

Interface and Connectivity

This processor connects to the LCN backbone through dual redundant coaxial ports. The 51403299-200 also provides 1 RS-232 service port for local diagnostics. Consequently, technicians can access fault logs without pulling the card. Two status LEDs report network health and processor activity directly on the faceplate.

Component Count and Build

Each 51403299-200 carries 1 processor board, 2 network transceivers, and 4 mounting ejectors. The board holds a 32-bit microprocessor with dedicated network memory. Furthermore, 8 firmware sockets allow controlled updates in the field.

Energy Storage and Power Parameters

The module draws 5 VDC and 12 VDC from the card cage backplane. A 0.22 F supercapacitor preserves configuration memory during short outages. Therefore, the 51403299-200 retains network settings through brief power interruptions. A 3.6 V lithium cell provides long-term backup for the real-time clock.

Key Technical Parameters

Integration Notes

The 51403299-200 slides into any free 2-slot position within the LCN card cage. Engineers set network addresses through the front service port before startup. Additionally, dual transceivers maintain link continuity when one path fails.
