Product Overview

The Honeywell 900TEK-0001 is a field termination assembly (FTA) and detachable terminal strip engineered specifically for the Honeywell ControlEdge HC900, Experion PKS, and Scan 3000 900 Series I/O subsystems . As a passive wiring interface, the Honeywell 900TEK-0001 provides a secure, organized, and maintenance-friendly bridge between field instruments—such as transmitters, solenoid valves, and proximity switches—and the active electronic I/O modules housed in the HC900 rack . The Honeywell 900TEK-0001 is a key mechanical accessory that eliminates point-to-point flying leads, reducing wiring errors and simplifying panel builds .

The core innovation of the Honeywell 900TEK-0001 lies in its detachable, plug-in design. It decouples the field wiring from the I/O module itself . All field cables are securely terminated onto the screw-clamp terminals of the Honeywell 900TEK-0001; the I/O module then plugs directly onto the terminal strip’s header. If an I/O module requires replacement or maintenance, the module can be removed and replaced—even hot-swapped in redundantly powered systems—without disturbing a single field wire . This small but critical accessory underpins the maintainability and wiring integrity of the entire Honeywell HC900 control-system installation .

Main Features and Advantages

Detachable Design for Maintenance Efficiency: The Honeywell 900TEK-0001 enables separation of field wiring from the I/O module . In the event of module failure, a technician can simply unplug the Honeywell 900TEK-0001 from the module, replace the defective card, and reinsert the terminal strip—no rewiring required. This capability is critical in continuous production environments where downtime is measured in minutes.

Secure Screw-Clamp Termination: The Honeywell 900TEK-0001 uses industry-proven screw-clamp terminals that accept wire sizes from 0.5 to 2.5 mm² (AWG 20-14) . This provides a robust, gas-tight connection that withstands thermal cycling and vibration, eliminating intermittent connection issues common with spring clamp designs. Each terminal is clearly numbered to match the I/O channel designation in Honeywell’s configuration software , significantly reducing wiring errors and accelerating loop-check activities .

Built to Outlast: The Honeywell 900TEK-0001 is a passive component with no active electronics, making it inherently reliable . The housing is constructed from flame-retardant 94V-0 rated plastic, ensuring fire resistance , while the nickel-plated copper alloy terminals provide excellent corrosion resistance . With a rated voltage of 300V and current capacity of up to 10A, the Honeywell 900TEK-0001 is suitable for most process control field circuits . It also offers a mechanical life exceeding 200 insertion/removal cycles .
