I-7590 RS-232/422/485 to M-Bus Converter for M-Bus Slave Devices
Converts RS-232, RS-422 or RS-485 serial traffic to an M-Bus network for reading meters and sensors. Serial and M-Bus baud rates are set independently using rotary switches.
- Serial port selectable as RS-232, RS-422 or RS-485
- Serial and M-Bus baud rates configurable separately, with 10 default and 6 user-defined baud rates
- Supports up to 100 M-Bus slaves
- Transparent communication between the serial bus and M-Bus
- 3750 Vrms photocoupler isolation on the M-Bus port
- Overcurrent and short-circuit protection on the M-Bus port

Product information "I-7590 RS-232/422/485 to M-Bus Converter for M-Bus Slave Devices"
The I-7590 bridges a serial host to M-Bus (Meter-Bus) slave devices. It accepts RS-232, RS-422 or RS-485 on the serial side and passes data through to the M-Bus network, so a standard serial master can poll energy counters, water and gas meters, and other M-Bus instruments without a custom protocol stack.
Serial and M-Bus baud rates can be configured separately. Ten default baud rates and six user-defined rates are available, allowing the converter to match a wide range of meter configurations. Transparent communication means the converter does not alter the data stream, and it supports up to 100 M-Bus slaves.
For reliability in the field, the M-Bus port has 3750 Vrms photocoupler isolation along with overcurrent and short-circuit protection. The unit also includes a watchdog, reverse polarity protection on the power input, and firmware can be updated through the RS-232 port. It mounts on DIN-rail and is rated for -25 ~ +75 ℃ operation.
Applications
- Remote reading of energy counters
- Hot and cold water meter reading
- Gas meter and gas counter reading
- Pressure sensors and actuators on M-Bus networks
