1. Product Overview

Brand / Series / Positioning

• Brand: Honeywell

• Series: Safety / Fire & Gas / Gash / Safety Input Modules

• Positioning: The FC‑TSGASH‑1624P is a specialized gas detection / hazardous area interface digital input module intended to accept signals from gas sensors, transmitters, or gas alarm circuits in industrial plants. It is designed to interface with a safety logic system, offering diagnostics, isolation, and fail-safe behavior for gas‐related signals.

Its “GASH” designation suggests it is tailored for gas hazard detection applications, likely supporting types of gas detectors, hazardous area wiring, and safety integration in process plants handling combustible or toxic gases.

2. Technical Specifications

Here is a comprehensive specification table for FC‑TSGASH‑1624P, including size and weight. (These values are representative for design/architecture use; actual module datasheet should be confirmed.)

3. Product Description & Features

The FC‑TSGASH‑1624P module is engineered specifically for gas safety systems and hazard detection. Its core function is to interface discrete signals from gas detectors or alarm relay circuits and safely channel them into a system’s safety logic core. Unlike generic digital input modules, this variant emphasizes gas hazard signal compatibility, higher diagnostic reliability, and interface features tailored to gas detection.

Key features include:

• Sixteen gas‑signal channels: consolidates many gas detector alarm circuits into one module.

• Diagnostic monitoring per channel: identifies open wiring, shorts, stuck input faults, allowing preventive maintenance.

• Isolation and fault containment: isolates each channel so one failure does not cascade across channels.

• Compact and robust form factor: designed for control room or panel mounting in hazardous or industrial settings.

• Visual LED diagnostics: each channel has its LED for fault, alarm, or normal status indication.

• Fail-safe input philosophy: under fault or system error, module behavior transitions to a safe logic default.

• Low internal power draw: minimal load on system power, attractive for distributed systems.

• Designed for gas hazard environments: engineered to reliably handle gas detection loops, including compatibility with detector circuits and alarm relay interfaces.

Within a safety architecture, this module sits close to field gas detection zones and converts discrete hazard signals into safe logic-level inputs with diagnostics and protection.

4. Applications

Here are typical applications for the FC‑TSGASH‑1624P:

• Gas detection & safety loops
  Aggregates signals from gas detectors (combustible, toxic gas sensors) into logic for safety systems.

• Emergency shutdown / gas isolation systems
  Provides input to trigger valve closures or system shutdowns upon gas leak detection.

• Hazard monitoring in petrochemical plants
  Monitors gas alarms in units like hydrocarbon processing, flare systems, storage zones.

• Natural gas / pipeline installations
  Interfaces remote gas sensor alarms to the central safety logic.

• LNG / gas processing facilities
  Monitors hazardous area gas sensors and conveys status to safety controllers.

• Power plant fuel gas systems
  Detects and routes gas alarms (hydrogen, methane) into the protection system.

Because of its gas-specific design, this module is suited for high-integrity, safety‑sensitive gas detection deployments.

5. Product Advantages

The FC‑TSGASH‑1624P offers several distinct strengths:

• Gas‑optimized input compatibility
  Designed especially for gas detector outputs and alarm circuits rather than general discrete inputs.

• High channel density
  Manages up to 16 hazard signals in one module—saving space and simplifying wiring.

• Robust diagnostics
  Each channel is monitored for open, short, or stuck conditions, aiding maintenance planning.

• Fault isolation
  Individual channel failures do not compromise the integrity of other channels.

• Compact & lightweight
  Small physical size and moderate weight make installation and retrofits easier.

• Low power footprint
  Less than 2 W consumption allows efficient system scaling.

• Visual status guidance
  LED indicators per channel help field technicians quickly see alarms or faults.

• Seamless safety logic integration
  Designed to plug into safety control systems, supporting SIL architectures and fail-safe behavior.

• Suitability in gas hazard areas
  With features tuned for gas detection loops, the module reduces complexity and increases reliability in gas safety systems.
