Overview
Configured for active bus termination and impedance matching, the Honeywell FC-TERM-0002 (FS-TERM-0002 Bus Terminator) provides direct electrical termination for a compatible control-system backplane or bus network. It presents a nominal 100 ohm termination and uses backplane power.

Bus Termination and Signal Integrity
The FC-TERM-0002 provides an active impedance-matching termination for the connected bus. Its specified 100 ohm termination resistance controls the electrical load presented to the bus.
The termination operates from backplane power, so the installation must provide the specified backplane supply connection. The supplied data lists a 500 VDC isolation rating from the backplane.
Signal reflection is specified below -30 dB at 1 GHz. Therefore, the terminator provides a defined impedance at high-frequency signal conditions. Correct physical installation also limits additional reflections caused by excessive conductor length, poor connections, or unsuitable routing.
The supplied specifications identify the component as a bus terminator rather than an analog or digital I/O channel. Consequently, 4-20 mA, HART, FOUNDATION Fieldbus, and CJC functions are not assigned to this component without additional manufacturer documentation.
Frequently Asked Questions
Q: What termination resistance does the FC-TERM-0002 provide?
A: The specified termination resistance is 100 ohm +/-1% at 0.25 W.
Q: How is the FC-TERM-0002 powered?
A: The unit is specified as backplane-powered. The supplied data also lists a 50 mA power requirement and a separate 15 mA current-draw reference at 24 VDC.
Q: What isolation rating is specified for the terminator?
A: The supplied specification lists 500 VDC isolation from the backplane.
Field Installation Guidelines
Install the terminator at the designated bus termination point specified by the control-system hardware documentation. Verify the correct connector orientation before applying backplane power.
Keep bus conductors routed according to the system wiring requirements. Avoid unnecessary conductor loops and maintain consistent routing near the termination point.
Use the specified cable and connector hardware for the associated bus. Keep signal wiring separated from high-energy switching conductors where the installation design permits.
Inspect the connector and termination interface for contamination, mechanical damage, or loose connections before commissioning. Verify that the backplane connection is fully seated.
After installation, confirm that the termination is present at the intended bus endpoint and that the system reports normal communication behavior. Do not add parallel termination components unless the system documentation explicitly requires them.
