Honeywell FC-TDOL-0724 CC V1.0 Field Termination Assembly

Configured for discrete output relay execution in Safety Manager control architectures, the Honeywell FC-TDOL-0724 CC V1.0 (FC-TDOL-0724) Field Termination Assembly provides direct physical/electrical execution across safety instrumented output loops. It manages relay switching operations at 24 VDC with channel current limits up to 250 mA, bridging system I/O modules with critical field actuators.

Hardware Specifications

Channel-to-Channel Isolation And 4-20 mA HART Loop Protocol

Operating within high-integrity safety instrumented frameworks, the assembly implements strict electrical isolation barriers across individual relay output paths to suppress common-mode noise and prevent cross-talk between safety loops. The physical layout ensures stable switching transitions for discrete safety interlocks. Furthermore, adjacent terminal blocks accommodate standard 4-20 mA HART loop protocol parameters and cold junction compensation (CJC) configurations when integrated into comprehensive process control panels.

Frequently Asked Questions

Q: Does the FC-TDOL-0724 CC V1.0 assembly support hot-swapping under power?

A: Hot-swapping field wiring on the termination assembly is restricted; loop power must be isolated and disconnected prior to servicing or replacing connected field devices to prevent arcing or unintended output activation.

Q: What are the primary electrical voltage and current limits supported by this termination unit?

A: The module is engineered for 24 VDC control circuits, accommodating a maximum continuous current rating of 250 mA per channel across its integrated relay output channels.

Field Installation Guidelines

1. Ensure all system power supplies and external loop voltages are completely switched off and locked out before handling or installing the termination assembly.
2. Mount the unit securely onto the designated DIN rail or mounting plate within the safety cabinet enclosure.
3. Terminate field actuator wiring and controller interface cables securely to the respective screw terminals, maintaining correct polarity.
4. Verify circuit continuity and insulation resistance parameters before energizing the safety loop.
