Product Overview

The Honeywell FTA-T-20 is a specialized Field Termination Assembly (FTA) designed for the Fail Safe Control (FSC) system, functioning as the high-integrity interface for digital output signal distribution. This module acts as the vital connection point between the safety logic solver and field-mounted actuators, such as solenoids, motor starters, and indicating lamps. Engineered to handle high-voltage switching requirements, the FTA-T-20 facilitates secure power distribution while providing physical isolation between the sensitive DCS electronics and the rugged field environment. Its architecture is optimized for safety-critical applications where deterministic switching and reliable circuit termination are essential for plant protection.
