Honeywell TG7-1H40S – Smart Link Terminal Board | TDC-3000 DCS Platform
Engineering Background: The Honeywell TG7-1H40S is a Smart Link Terminal Board designed for integration within Honeywell’s TDC-3000 Distributed Control System (DCS) architecture. As a critical interface component, it bridges field wiring to the Smart Link highway, enabling reliable signal routing and I/O termination in process automation environments across refining, petrochemical, power generation, and advanced manufacturing facilities.
Product Positioning: Engineered for procurement engineers and control system integrators who require a verified, drop-in replacement or expansion module for existing TDC-3000 installations. The TG7-1H40S delivers OEM-specification performance with full backward compatibility, minimizing re-engineering costs and downtime risk during system upgrades or maintenance cycles.

System Architecture & Signal Flow
The TG7-1H40S interfaces field instrument wiring (4–20 mA, discrete I/O, or thermocouple inputs depending on paired I/O module) to the Honeywell Smart Link Highway. Field cables terminate at the board’s screw-terminal blocks; signals are conditioned and routed via the Smart Link bus to the associated Process Manager (PM) or High-Performance Process Manager (HPPM) controller. The terminal board mounts in the standard Honeywell I/O cabinet and mates with the corresponding I/O module via the backplane connector, maintaining full galvanic isolation and signal integrity across the control loop.

Technical FAQ
Q: Is the TG7-1H40S compatible with both TDC-3000 and Experion PKS systems?
A: The TG7-1H40S is designed for the TDC-3000 Smart Link architecture. Compatibility with Experion PKS depends on the specific I/O subsystem configuration — please consult your Honeywell system documentation or contact us for clarification.
Q: Can this terminal board be used with any I/O module, or is it paired to a specific type?
A: The terminal board is paired with a specific I/O module type (analog input, analog output, or digital I/O) as defined in the TDC-3000 cabinet design. Confirm the paired module part number from your cabinet drawing before ordering.
Q: Do you provide installation support or commissioning assistance?
A: We provide technical documentation and pre-sales engineering consultation. On-site commissioning is the responsibility of the end-user’s qualified control system engineer.
Q: What is the lead time for this part?
A: Typically 3–7 business days for in-stock units. Contact us for real-time availability confirmation.
Q: Is a Certificate of Conformance (CoC) available?
A: Yes. CoC and inspection reports are available upon request at time of order.
