M-BUS to USB Master Converter for Data Debugging, Testing, and Communication for Electricity and Hea

Complies with EN1434-3 and Chinese standard CJ/T188-2018. Very low static power consumption with short circuit protection. USB hot plug for safe and stable operation. Robust USB-B interface. Compatible with Windows 11, MacOS, Linux, and Android. USB powered, no external power supply needed. Compact shell design for easy field commissioning and portability. Supports up to 15 standard slave devices on average, with a maximum load of 20. No spontaneous self-reception or bit errors within normal load range. Baud rate from 300 to 9600 bps, supporting up to 19200 bps. Long communication distance up to 1 km, with bit error rate lower than 0.01%. Connect slave stations (water, heat, gas meters) in parallel to the interface. Plug the USB module into a computer USB port; the status indicator lights up. Load capacity: Bus maximum load current Ic = 80 mA. Static current of slave station = IS, dynamic current = It. Load quantity N = (Ic - It) / IS. For maximum static current IS = 5 mA and dynamic It = 20 mA, N = (80 - 20) / 5 = 12. For standard static current IS = 3 mA and dynamic It = 20 mA, N = (80 - 20) / 3 = 20.
