SES GAS2402 Model 2402 Industrial Gas Detection Controller

The GAS2402 (2402) is a dedicated gas detection and alarm controller for industrial hazardous environments. It receives sensor signals and continuously monitors the concentration of combustible or toxic gas, and triggers local alarms or relay outputs once gas concentration exceeds preset thresholds.

This wall‑mounted controller features digital concentration display, fault self‑diagnosis and relay alarm contacts. Original production has been discontinued. It is available as aftermarket spare parts for oil & gas, chemical and wastewater gas monitoring system maintenance and retrofitting.

Main Specifications

Core Functions

1. Receive 4‑20mA analog signals from field gas sensors and convert data into gas concentration values.
2. Compare real‑time concentration with high/low alarm setpoints and activate relay alarm outputs automatically.
3. Detect sensor failure, circuit disconnection and power abnormality and send fault warning signals.
4. Display real‑time gas concentration and alarm status on the front digital screen for on‑site checking.
5. Link with exhaust fans, solenoid valves and safety interlock devices to reduce gas leakage risks.
6. Work as the central control unit of fixed industrial gas safety monitoring systems.

Application Scenarios

1. Gas leakage safety monitoring for chemical plants, oil depots, sewage treatment and boiler rooms.
2. Spare controller replacement and daily maintenance of existing GAS2402 gas alarm systems.
3. Technical renovation and safety upgrade of aging fixed gas detection and interlock systems.
4. On‑site troubleshooting and replacement of faulty gas controllers in hazardous production areas.
5. Spare‑parts stocking for system integrators and fire & safety automation maintenance contractors.
6. Global aftermarket spare supply for technicians maintaining obsolete industrial gas monitoring hardware.

FAQ

1. Q:Does GAS2402 2402 include gas sensors?
   A:It is only a controller and needs to be matched with external 4‑20mA gas transmitters.
2. Q:Can it realize automatic safety interlock?
   A:Yes, the built‑in relay contacts can drive ventilation equipment and cut‑off valves.

3. Q:Is this gas monitoring controller still in original production?
   A:The manufacturer has stopped producing this model, only tested surplus and refurbished spare units are available.
