The GT-2511-FLP is a Flameproof, PESO Certified Smart Gas Detector designed for swift and reliable detection of Oxygen, Toxic, Combustible, and Volatile Organic Compounds (VOC) gas leaks. Featuring an 8 x 2 Alphanumeric LCD with configurable backlit and 8 LEDs for status indication, it provides a clear digital display of gas concentration. The device offers a standard 4-20mA signal output with a configurable range and three relay outputs with a 5A rating. Optional Isolated RS-485 Communication Port with MODBUS RTU PROTOCOL enhances connectivity. With a hot-swappable gas sensor module, the detector ensures easy maintenance, storing calibration data, alarm data, offset data, and output current data in the sensor module. Non-intrusive programming for the Flameproof Model is facilitated using a Magnetic Wand. The detector is capable of detecting gas concentrations down to PPM, %V/V, %LEL, and mg/m³, with indications for ‘Sensor Open,’ ‘Over Range,’ ‘Sensor Replace,’ ‘Cal Due,’ ‘Cal Fail,’ and mA Loop Open for comprehensive monitoring.
