Honeywell TDC 3000

The Honeywell 51402610-200 is a TPDGX (Turbo Peripheral DG) board for the Universal Station (USX) within Honeywell's TDC 3000 distributed control system.

The Honeywell 51401946-100 is a Memory Processor Module for the TDC 3000 distributed control system.

The Honeywell 51401497-100 is a dual-node power supply module designed for the TDC 3000 distributed control system's dual-node LCN chassis. It provides independent, redundant DC power to two separate nodes (such as Universal Stations), ensuring that if one power channel fails, the other continues to operate without interruption. 

The Honeywell 51401291-100 is a Low Power Local Control Network (LLCN) board designed for the TDC 3000 distributed control system. It functions as a network interface card that handles token ring protocol execution and data forwarding within the LCN, ensuring reliable communication between system components.

Honeywell 51401088-100 is a Communication Network Interface Board used in Honeywell TDC 3000 control systems, enabling network communication between system nodes.

Honeywell 51400972-100 is a Keyboard Interface module for the Honeywell TDC 3000 distributed control system, serving as the interface electronics between the operator keyboard and the system.

Honeywell 51400855-100 is a control board module designed for Honeywell TDC 3000 distributed control systems (DCS). It executes control logic and interfaces with the Local Control Network (LCN), featuring industrial-grade construction for reliable performance in demanding process control environments.

The Honeywell 51400756-100 is an "ABCDE" Membrane Keyboard Section for legacy Honeywell TDC 3000 Universal Station operator consoles. It is a passive tactile input layer (the physical key surface) that must be paired with a separate internal keyboard interface board to function.

The Honeywell 51400712-100 is a 5-Slot Chassis Power Supply used in Honeywell TDC 3000 (and TDC 2000) distributed control systems . It is the original power supply for the 5-slot chassis equipped with an 8-pin power connector, typically found in LCN nodes and Universal Stations.

The Honeywell 51305508-200 is an XLCNE2 Paddle Board for the Honeywell TDC 3000 distributed control system.

The Honeywell 51305072-900 is a CLCN-B I/O Board within the Honeywell TDC 3000 family.

The Honeywell 51305072-600 is a K2LCN-B I/O Board, also a CLCN-B board for the Honeywell TDC 3000 distributed control system.
