The RS485toMBus-4M converter provides a RS485 to M-Bus interface conversion. There is no change in the content of the messages or communication speed during the conversion. The maximum number of M-Bus slave devices that can be connected is five.
M-Bus port
• Connection of 1 to 4 M-Bus slave devices.
• Surge protection guaranteeing superior durability against overvoltage.
• Current protection against overload and short circuit on the communication line with
• LED status indication.
Power supply
• Wide range of DC power supply voltage 7-28V.
• Overvoltage protection with LED indication of power supply.
RS485
• Signals: Data+, Data- and GND
• Protections against overvoltage.
• Selectable termination of the line with a 120R resitor.
• Galvanic separation from the M-Bus line.
Mechanical construction
• Plastic box with mounting on 35 mm DIN rail.
• Each converter passes through several functional electrical tests during the production.
Additionally a communication test is performed after final assembly.
• EMC certification in an accredited laboratory for industrial environment.
• Solid design and construction based on many years practical experience.
