PW60

Function of the Master-PW devices

Signal processor driven M-Bus Master / Level-Converter for 60 slaves

The devices in the PW series are M-Bus master interfaces for networks with 3, 20 and 60 slaves.

They are compact in design (wall or rail mounting) and have a broad supply voltage range. The actual operating state is indicated by several LED at the front. All device versions in the PW series are equipped with a RS232 port. The control computer can communicate with the M-Bus meters by the integrated IR optical interface using a ZVEI optical head.

The PW60 has an additional noise free RS485 port which enables greater distances between control computer and level converter.
