Technical design Signal converter As a signal converter, the WZC-P60 converts RS-485, RS-232 or optical signals to Mbus signals. The signals between input and output are galvanically separated by means of optocouplers. Bus driver As a bus driver, the WZC-P60 supplies a maximum of 60 M-bus devices with the bus zero-signal current. The M-bus output of the signal converter is protected against shortcircuits. Power supply Power is supplied via an external power pack.
