A unique approach to digital and analog gas detection control
Sep 10 2020 Read 222 Times
The new Q-Controller, from QEL, includes features that are unique to the gas detection industry. The system uses an RS-485 communication protocol that accommodates 128 channels through four digital ports. In addition, there are 128 analog inputs from any 4-20 mA device and equally 128 4-20 mA outputs. There are also up to 128 binary inputs and 128 binary outputs.
Modbus output from the controller is a standard feature as well as an available BACnet IP output. The system communicates wirelessly for programming and downloading of data through your smartphone or tablet device. Input/output boxes can be installed anywhere in the RS-485 network for ease of installation of additional sensors. A touch screen graphic display is used for programming.
All relevant gas detection data, such as relay status, historical data, location and addresses of sensors are displayed by scrolling through multiple screens. The controller has a scheduler that can be programmed to activate relays and deactivate relays several times a day based on a frequency of day, weekday or weekend only. It also has an auto-configure program that searches for connected devices. As the unit can accept any 4-20 mA signal it is ideal for additional monitoring such as temperature humidity and other parameters that may be of interest. Several Q-Controllers can be connected together to a centralized system that will display gas detection concentrations of an entire facility. Remote monitors are an optional item that can be used to observe the concentration of gases prior to entering the space.
