Honeywell 05425001 054250-01 TDC 3000 Termination Boards

Configured for field wiring interconnections in TDC 3000 systems, the Honeywell 05425001 054250-01 (05425001 Termination Board) provides direct physical/electrical execution. This compact interface board establishes electrical contact points between field instrumentation wiring and internal DCS control processors. Housed in a durable plastic structure measuring 25.9 x 19.3 x 1.0 cm, the unit organizes field conductors across multiple terminal points to streamline signal routing and prevent cross-wiring errors inside high-density control cabinets.

Hardware Specifications

DCS Process Control & Interface Wiring

The termination assembly routes field instrument signals to system processing hardware using passive electrical connections. Built-in channel-to-channel isolation layouts prevent inter-channel cross-talk and maintain signal purity across parallel wiring runs. The board operates under 4-20 mA HART signal protocol environments and accommodates discrete control circuits without introducing signal distortion or loop resistance shifts. Thermal tolerance across -40 to 85 deg C ensures stable electrical contact resistance even under elevated enclosure temperatures.

Frequently Asked Questions

Q: Does this passive termination board consume power from the backplane?

A: No, the board functions as a passive physical interface board for signal routing and does not draw operational power from the system backplane.

Q: What grounding precautions must technicians follow when landing shielded field cables on this board?

A: Technicians must terminate overall cable shield drain wires directly at the central cabinet earth ground bar rather than floating them on unused terminal points to prevent ground loop noise.

Field Installation Guidelines

Mount the termination board securely inside the control cabinet using designated panel retention screws. Strip incoming field wires to 6 mm and secure them into the terminal connection points, verifying tight mechanical contact without over-torqueing the screw clamps. Route field signal cables away from high-voltage AC lines by maintaining a minimum separation distance of 300 mm to prevent electromagnetic interference. Ensure that all shield drain wires connect directly to a single cabinet ground point to eliminate ground potential differentials.
