1. Product Overview

The 05701-A-0361 module is specifically designed to monitor flammable gases in the environment, such as methane, hydrogen, hydrocarbons, and others. It is typically installed in a System 57 19-inch rack or cabinet, working in conjunction with front-end gas detection probes to display gas concentrations in real time and trigger alarms when levels exceed thresholds.

2. Key Features

Signal Processing: Receives signals from catalytic combustion (pellistor) or infrared (IR) gas sensors.

Concentration Display: Features a four-digit LED numeric display on the front panel, showing real-time gas LEL (Lower Explosive Limit) percentage.

Alarm Level Configuration: Supports three alarm levels (A1, A2, A3) with user-configurable thresholds.

Multi-State Indication: LED indicators display “Power,” “Alarm,” “Fault,” and “Inhibit” statuses.

Relay Output: Equipped with a programmable relay for activating audible/visual alarms, fans, or automatic shut-off valves.

3. Application Scenarios

This module is widely used in industrial settings requiring strict monitoring of flammable/explosive gas leaks:

Oil & Gas: Oil platforms, refineries, LNG storage tank areas.

Chemical/Pharmaceutical: Workshops involving flammable solvents or chemical reactions producing combustible gases.

Energy & Power: Gas turbine rooms, hydrogen storage facilities.

Water Treatment: Areas within wastewater treatment plants where methane (biogas) may be generated.
