Model YZ1001B/C Gas Detection Controllers (RS485/ 4-20mA)
Gas Detector & Controller
Combustible/toxic gases detection controller
for Fixed Gas Detection
8 CHANNEL Gas detection controllers for combustible/toxic gases detectors
Brief Introduction
The controller receives the data from the matched detector transmitters. After high-speed processing, the gas concentration and other states from the detectors are displayed on highlighted LED screen. They are set up to trigger other safety measures, so they can open vents, start fans, close valves or even shut processes down automatically once they detect a problem. They can also set off alarms to begin an evacuation.
Features
High Stability
High-speed industrial single chip microcomputer based, which is stable, reliable and does not crash.
High Security
DCDC isolated power supply ensures safe and reliable operation of the circuit. The isolated voltage is 1.5kVDC.
The bus control cabinet (RS485) is isolated at both ends (input and output), with an isolation voltage of 2.5kVDC.
Optocoupler isolation chip is used to isolate input and output terminals for analog input (4-20mA). The isolation voltage is 1.5kVDC.
Visual Display
The value of gas concentration can be seen clearly in LED display even under hard light.
Intelligence
●Self-checking and self-diagnosis.
●For analog input (4~20) mA, 1~8 optical coupler isolation acquisition modules can be selected as required.
