Product Overview
The Honeywell FTA-T-17 functions as a high-integrity Digital Output Field Termination Assembly (FTA) specifically engineered for Fail Safe Control (FSC) systems. This module provides critical electrical isolation and secure switching for field devices such as actuators, solenoids, and safety alarms. Optimized for AK5 and AK6 safety-rated applications, the FTA-T-17 ensures that control commands execute with absolute fidelity. We supply this module as 100% Brand New and Original, providing the hardware-level assurance required for high-risk industrial safety loops.

Engineering Advantages
-
Triple Relay Redundancy: Each of the four output channels utilizes three internal relays in a voting or series configuration. This architecture prevents a single welded contact or coil failure from compromising the safety function, meeting the strict requirements of AK5/AK6 standards.
-
Integrated Circuit Protection: Every channel features built-in fused normally open (NO) contacts. These fuses protect the internal module circuitry from field-side overcurrent conditions and short circuits, localized to the affected channel.
-
Visual Diagnostic Feedback: High-visibility LED status indicators provide real-time confirmation of the output state for each channel. This allows maintenance personnel to verify command execution instantly without opening the loop or using external multimeters.
-
High-Density Safety Marshalling: The compact 160mm footprint enables engineers to mount multiple units on a single DIN rail. This reduces the total enclosure size required for complex safety instrumented functions (SIF) while maintaining clean, organized wiring paths.
FAQs
What is the significance of the AK5/AK6 rating for the FTA-T-17?
AK5 and AK6 are German safety standards (Anforderungsklasse) used in Fail Safe Control systems. This rating confirms that the FTA-T-17 possesses the necessary hardware redundancy and diagnostic coverage to manage high-risk process hazards where failure is not an option.
Can I replace a standard non-safety relay with the FTA-T-17?
While the FTA-T-17 performs relay switching, its triple-redundant architecture is specific to Honeywell FSC systems. It requires a 24VDC safety signal from the FSC controller to energize the redundant relay coils correctly.
What happens if a single relay fails within a channel?
Because each channel uses three redundant relays, the system maintains its fail-safe state. The redundant design ensures that the output will still open or close as required by the safety logic, providing a window for maintenance before safety integrity is lost.
Does this module ship with original factory certifications?
Yes. Every FTA-T-17 unit we provide is 100% Brand New and includes the necessary industrial certifications (CE, TUV, UL508) required for deployment in regulated safety-critical environments.
