PLT200-4 Gas Alarm Controller
Key words:
This series is a 2- to 4-channel body alarm controller.It consists of a common metal case, a switching power supply board, a connector board, and an alarm (batteries are optional).The body alarm controller (hereinafter referred to as the controller) can be combined with our body detectors with 4-20mA current output or RS485 signal output to form a body alarm control system for industrial use.When a measured substance or liquid evaporates in the air, the detector creates a current signal that is proportional to the concentration of the measured substance in the air, and this signal is transmitted to the controller, which processes it and displays the concentration of the measured substance.When the concentration of the measured substance reaches or exceeds the set value, the controller emits an acoustic and optical alarm signal and the relevant control signals to activate the corresponding control devices, thus preventing the occurrence of a serious accident.The product is modular in design, i.e., one gas detector for each channel is used in conjunction with the appropriate detector.
