Honeywell FTA-T-08 Fail-Safe Digital Output Module

Overview

The Honeywell FTA-T-08 is a fail-safe digital output Field Termination Assembly (FTA). It supports four independent relay contact channels for controlling solenoids, lamps, and actuators. Each channel features dual redundant relays from different manufacturers to enhance operational safety and reliability. Designed specifically for Honeywell Safety Manager systems, the FTA-T-08 ensures precise, secure control in critical industrial applications.
