RS485/M-Bus convertor (45/80/120/190 devices)

A durable communication converter of the M-Bus industrial bus to RS485 serial interface. The device is available in four variants differing in the maximum number of connected slave devices (45, 80, 120 or 190). 

RS485toMBus-XL is a durable converter designed primarily to collect data from M-Bus metering devices and convert the data for the standard RS485 serial interface. Signals are converted directly without the need to set up communication parameters or adjust the messages. 

Based on the variant up to 190 M-Bus slave devices can be connected to the M-Bus interface, with the M-Bus and converter states being monitored by converter's processor. Five LEDs are available for indication of M-Bus states and error states. The M-Bus interface features the highest class of overvoltage protection and is also protected against communication errors, inverted power supply polarity and continuous short circuits. 

Components of the converter are encased in a durable aluminium chassis, providing the device with a high degree of mechanical durability and reducing the effect of interference. The converter is designed for standard 35mm DIN rail installation.
