PRODUCT INTRODUCTION
The GL101-S/R M-BUS converter is primarily designed to convert the M-BUS bus to RS485 or RS232, enabling host devices that do not have an M-BUS master interface to communicate with M-BUS slave devices (e.g., water meters, thermostatic valves). This series is designed to industrial-grade standards, featuring excellent characteristics such as wide operating temperature, wide input voltage range, and strong driving capability. The core circuitry has been verified through years of field use across various industries, ensuring stable and reliable operation.
