MPW-6 Level converter RS485/M-Bus

With the optec-MPW-6 M-Bus level converter, up to 6 M-Bus end devices (each with a standard M-Bus load of 1.5mA) can be connected to an M-Bus master via an RS-232 connection or RS-485 interface. The M-Bus master can be a PC or an embedded controller, for example. The level converter converts the signals coming from the M-Bus master from the RS-232 or RS-485 interface to M-Bus signals.
