Detcon’s (USA) state-of-the-art Model 700 gas detection sensors now include wireless technology as an integration option. All 700 sensors are equipped with standard 4-20mA analog and Modbus RS-485 outputs. The Model RXT-300, Detcon wireless gas detection system, is designed to work with 700 sensors and other Field devices with an RS-485 Modbus serial output. The RXT-300 is a wireless Modbus replacement and links one master to one or more slaves. Additional communication solutions for the Model 700 include HART, Foundation fieldbus, Profibus, and a recently mechanically repackaged Remote Sensor/Alarm Relay Module.
