Can connect various gas detectors, temperature and humidity transmitters, pressure transmitters, wind speed transmitters, dust detectors, and other 4-20mA signals,
Units available: PPM, LEL%, Vol%, mg/m3, milligrams per cubic meter, PPHM, ℃ RH%、Pa、 Kilogram PSI、 M/S
At the same time as 4-20mA input, RS485 input and RS485 output (standard MODBUS protocol) are available. Optional: 8 channels of 4-20mA output
Modular structure design, standard channel is 1 (32 channels) 4-20mA input signal, and can also connect 255 RS485 input signalsNumber, more channel input signals
The gas alarm controller has data recording function, with a standard capacity of 100000 pieces, and larger capacities can be customized. Storage time interval can be set arbitrarily
Three display modes can be switched: displaying 6-channel concentration per screen, large font cyclic display of single channel concentration, real-time curve, and between channels
Gas alarm controller with computer monitoring function, can be connected to a computer to continuously monitor real-time concentration 24 hours a day through upper computer software
The gas alarm controller has remote transmission function, and the controller can transmit the real-time concentration of the on-site probe through wired communication (within 2000 meters)
