Product Description

High-Integrity Digital Signal Interfacing

The Honeywell FC-TSGASH-1624P is a high-performance Digital Input/Output Field Termination Assembly (FTA) designed for the Honeywell Safety Manager and Fail Safe Control (FSC) systems. This module serves as the critical physical interface between field-mounted discrete devices and the central controller. Engineered to handle 16 channels of safe digital signals, the FC-TSGASH-1624P facilitates the transmission of ON/OFF states for critical monitoring and actuation. Its specialized circuitry is optimized for 24 VDC operation, providing the robust electrical backbone required for modern Safety Instrumented Systems (SIS).

Safety Engineering and Fault Protection

Designed with a "safety-first" philosophy, the FC-TSGASH-1624P features individual current limiting for every channel. This ensures that a field-side short circuit on a single sensor or actuator remains isolated, preventing a localized fault from causing a system-wide power collapse or loss of the remaining 15 channels. The module provides full galvanic isolation between the field wiring and the sensitive system bus, shielding the controller from electrical noise and transients. Housed in a compact, DIN rail-mountable form factor, it is rated for extreme industrial temperatures (-40 °C to +70 °C) and is certified for use in Class I, Division 2 hazardous areas, making it a staple for offshore platforms, refineries, and chemical processing plants.
