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

The Honeywell FC-TDOL-0724 CC V1.0 is a 7-channel line-monitored relay-contact digital output Field Termination Assembly (FTA) designed for Honeywell Safety Manager systems. It provides safe interface isolation and continuous line monitoring for high-integrity field circuits operating up to SIL 3 safety standards.

Line Monitoring and Output Control

The assembly handles physical field switching across 7 discrete output channels, delivering 24 VDC nominal operating power at up to 2 A per channel. Each output path incorporates continuous loop integrity checks to detect lead breakage and external short circuits, ensuring instant fault identification before or during control action.

System Integration and Circuit Protection

To protect field wiring and upstream controller logic from transient overcurrent events, each output channel is equipped with individual time-delay fusing. The conformal-coated (CC) board construction provides extra resilience against harsh industrial atmospheric conditions within control cabinets.

Frequently Asked Questions

Q: What type of circuit monitoring does the FC-TDOL-0724 CC V1.0 perform? A: The FTA continuously conducts loop integrity checks across its 7 field channels to detect line breakage and short-circuit conditions in discrete field wiring.

Q: How are individual output channels protected against overcurrent conditions? A: Each output channel features an integrated time-delay fuse to protect field circuits and safety controller outputs from current surges.
