Honeywell 51403299-100 Processor Board for Local Control Networks

The 51403299-100 processor board handles the core computing tasks inside Honeywell local control network nodes. This board executes control algorithms and manages data flow between network components. Plant engineers depend on its stable performance in continuous process environments.

Physical Dimensions and Weight

The 51403299-100 measures 178 mm in height and 40 mm in width at the faceplate. Its circuit board extends 160 mm in depth behind the front panel. The unit weighs approximately 0.45 kg, which keeps card cage loading balanced during routine service.

Interface and Connectivity

This board links to the network backplane through a 96-pin DIN connector. The 51403299-100 also offers 1 RS-232 diagnostic port on the faceplate. Consequently, technicians can read fault codes without removing the card. Two LEDs indicate board status and network activity during operation.

Component Count and Build

Each 51403299-100 carries 1 main processor, 4 memory modules, and 2 network interface chips. The board includes 8 firmware sockets for field updates. Furthermore, 2 ejector levers simplify card removal from tight cage positions.

Energy Storage and Power Parameters

The board draws 5 VDC and 12 VDC from the backplane supply rails. A 0.22 F supercapacitor holds configuration data through brief outages. Therefore, the 51403299-100 keeps critical settings intact during short interruptions. A 3.6 V lithium cell backs the real-time clock for long-term retention.

Key Technical Parameters

Integration Notes

The 51403299-100 fits any compatible slot within the Honeywell LCN card cage. Engineers configure node addresses through the front diagnostic port before startup. Additionally, the ejector levers prevent connector damage during hot maintenance swaps.
