The Honeywell FC-TSDO-1624 is a high-integrity Digital Output Field Termination Assembly (FTA) specifically engineered for the Honeywell Fail-Safe Controller (FSC) and Safety Manager platforms. This module acts as the critical physical interface between the safety processor and field-mounted actuators. It converts internal logic commands into 24 VDC electrical outputs to drive essential safety devices such as solenoids, relays, fire dampers, and audible alarms. Designed for high-availability environments, the FC-TSDO-1624 ensures that safety-critical actions are executed with millisecond precision while maintaining strict galvanic isolation between the field and the control system.
A key feature of the FC-TSDO-1624 is its per-channel current limiting architecture. This safety-focused design ensures that an electrical short circuit on a single field device will not cause a voltage drop across the entire module, effectively preventing system-wide failures and maintaining the operation of the remaining 15 channels. The module is housed in a rugged, DIN rail-mountable assembly, rated for an extended temperature range of –40 °C to +70 °C. This makes it suitable for deployment in unconditioned industrial cabinets and Class I, Division 2 hazardous locations. Integrated LED diagnostics provide immediate visual feedback on the status of each output, significantly reducing mean time to repair (MTTR) during maintenance cycles.
