DOUBLE CHANNEL CONTROLLERS
The double gas alarm controller is a smart controlled system that is practical and easy operated. It can be connected to the gas sensor that with 4-20mA signal output, to realize remote control and system integration. It is compatible to different kinds of gas sensors, mainly use for areas that need to measure combustible or toxic gases, which can show the gas concentration directly, and when the gas concentration reaches to the alarm point, the controller will alarm with sound and light. The controller is also with relay output, which can control the exhaust fan and other devices, to realize intelligent and automatic operation.

Touch screen operation, more convenient
7-inch touch screen, all the daily operations can be done through the touch screen
The high brightness touch screen shows the local time, detected gas, gas concentration, unit, the current probe is normal, etc 24h online.
Multiform signal output function
Standard RS485 signal output (optional)
3 channel relays and 1 common relay output
Data storage and alarm functions
Can save 1000 gas alarm records and it’s very convenient for the operator to have a knowledge of the alarm status
Two alarm function, when the gas concentration reaches the preset alarm value, the controller will generate sound alarm
Strong compatibility
Compatible with different kinds of gas detectors, can be connected to 2 digital communication mode bus detectors, without interference to each other.
Transmission distance
The maximum distance between the detector and the controller is less than 1000 meters, and the maximum distance between the computer and the controllers is less than 1000 meters
Durable
Waterproof and dustproof, can withstand the highest standard test, IP65 protection grade
Check all relays in real time to ensure the system runs without obstacles
