Honeywell 51403282-100 Local Control Network Processor Board

The 51403282-100 processor board drives communication and control logic inside Honeywell local control network nodes. This module coordinates data traffic between controllers and operator interfaces. Maintenance teams value its predictable behaviour in demanding process plants.

Physical Dimensions and Weight

The 51403282-100 presents a 178 mm faceplate height and a 40 mm faceplate width. Its circuit board reaches 160 mm in depth behind the front panel. The assembly weighs roughly 0.45 kg, which eases handling during card cage service.

Interface and Connectivity

This board mates with the network backplane through a 96-pin DIN connector. The 51403282-100 additionally offers 1 RS-232 diagnostic port on the faceplate. Consequently, engineers can pull fault logs without disturbing rack wiring. Two front LEDs report board health and network traffic in real time.

Component Count and Build

Each 51403282-100 carries 1 main processor, 4 memory modules, and 2 network interface chips. The design includes 8 firmware sockets for controlled field updates. Furthermore, 2 ejector levers simplify insertion and removal in dense cages.

Energy Storage and Power Parameters

The board draws 5 VDC and 12 VDC from the backplane supply rails. A 0.22 F supercapacitor preserves configuration data through brief outages. Therefore, the 51403282-100 retains critical settings during short power interruptions. A 3.6 V lithium cell backs the real-time clock for long-term retention.

Key Technical Parameters

Integration Notes

The 51403282-100 fits compatible slots within the Honeywell LCN card cage. Engineers set node addresses through the front diagnostic port before startup. Additionally, the ejector levers protect connector pins during hot maintenance swaps.
