User manual for Teledyne MX 40 wireless gas detection controller with mesh network, up to 16 BM 25 units, and SD data logging.
The MX 40 is a wireless gas detection controller that centralizes measurements from up to 16 BM 25 units via a mesh network. It supports various input/output modules and includes features like a back-lit LCD, SD memory card for data logging, and RS-485 Modbus RTU output. The system operates on 2.4 GHz frequency with a range of up to 5000 meters in open field. It also offers remote access via web interface and optional GSM/Ethernet for alerts.
The MX 40 supports multiple detector types including 4-20 mA analog, RS485 digital, and BM 25 wireless units. It has 64 programmable relays, 3 LED alarms, IP54/NEMA 4X protection, and operates from -20°C to +70°C. Two versions exist: MX40-08 (smaller enclosure, max 6 modules) and MX40-32 (larger, max 12 modules).

The MX 40 is a gas detection unit that communicates via radio to the BM 25 wireless units. This makes it possible to centralize all of the measurements recorded by the BM 25s in one location and to adjust settings.
The MX 40 controller can manage up to 16 wireless BM 25 units, including up to 32 measurement channels.
The maximum range between network nodes is 1000 meters, open-field. Because the same message can be relayed 4 times, the maximum distance between a node and an MX 40 unit can reach up to 5000 meters.
Yes. The MX 40 comes standard equipped with an SD memory card for recording measurements, min/max, averages, and fault, alarm and calibration events.
