Description
Overview
The Honeywell 51401286-100 PC Board is an Enhanced Peripheral Display Generator designed for integration with Universal Station nodes within Honeywell distributed control architectures. This board functions as a specialized interface module responsible for managing peripheral display operations and supporting SCSI-based communication within the system infrastructure.
Installed in operator workstation environments, the 51401286-100 board enables reliable acquisition and handling of digital signals originating from field instrumentation, relays, and discrete sensors. It translates these inputs into system-readable data that can be processed by supervisory control software in Honeywell control platforms such as TDC 3000 and Experion environments.
The board is engineered for continuous industrial operation and provides stable signal conditioning, electrical isolation, and high-speed response to maintain deterministic system performance.

FAQ
What is the primary function of the 51401286-100 board?
The board acts as a peripheral display generator and digital signal interface for Universal Station nodes, enabling communication between field inputs and the operator workstation display system.
Is the module compatible with Experion PKS systems?
Yes. While originally developed for Honeywell TDC 3000 architectures, it can also operate within environments where Experion PKS maintains backward compatibility with legacy hardware.
Does the board require external signal conditioning?
In most installations no additional conditioning is required because the board includes internal isolation and input handling for typical 24 VDC discrete signals.
