Product description
With the MPW-64 M-Bus level converter, up to 64 M-Bus end devices (each with a standard load of 1.5mA) can be connected to an M-Bus master via an RS-232 connection. The level converter converts the signals coming from the M-Bus master from the RS-232 interface to M-Bus signal levels. The M-Bus master is connected to the level converter either via an RJ-12 socket or terminals 5 to 7 (TD, RD and GND).
Technical features:
- Supply voltage 20V to 28V AC/ DC
- M-Bus voltage 36V to 42V
- Max. M-Bus quiescent current 90mA (60 standard loads)
- Overcurrent threshold 110mA
- Galvanic isolation between RS-232 and MPW-60
- Transmission rate RS-232: 300 ... 9600 baud
