Major Features
● Meet the need of connecting standard 4-20mA current signal detectors at 1-4 point locations;
● With a small size, the product can be wall-mounted easily. Two sets or more can be installed side by side to meet customer’s demands for more point locations (wall mounting of 8, 12, 16 or more point locations can be realized through gapless combination);
● Monitoring and display of real-time concentration (%LEL, 10-6, %VOL) as well as switching value signals of combustible gas, toxic gas and oxygen (default is combustible gas detector. No setting is required. It is available for use after being installed and electrified);
● Each circuit links one switching value output. If necessary, linking programming setting can be realized through the menu. Each product has one RS485 digital interface to communicate with the host computer;
● The visual range is farther and the visual angle is wider. Concentration contains 4 effective digits. Display with an accuracy of 9999~0.001 is available;
● Save the latest 999 alarming records and 999 failure records.

Panel Marks And Mounting Instructions
● Make 4 or 6 mounting holes (hole depth: ≥40mm) in a wall according to the requirements for the size among mounting holes (hole symbols 1 – 6) for mounting the hanging plate;
● Insert a plastic expansion bolt into each mounting hole;
● Fix the hanging plate onto the wall and fasten it onto the expansion bolts with 4 or 6 self-tapping screws (ST4.2×25);
● Hang the hanging parts at the bottom of the controller onto location A at the bottom board to complete mounting of the controller.
System Configuration
AEC2392b has 4 sets of branch-line connection terminals that can be connected to the branch-line communication equipment manufactured by the company such as detectors AEC2232b, AEC2232bX, GQ-AEC2232b, GQ-AEC2232bX and AEC2232aT, or other transmitters with 4~20mA signal outputs to monitor and control the gas concentration at site. Meanwhile, remote logical control over external equipment (in-situ audible-visual, solenoid valves and fans, etc.) can be realized through 5 sets of built-in programmable modules. In addition, remote communication with the monitor system can be realized through the RS485 communication interface.
