Function of the PW50

The Pw50 is a modern M-Bus master for 50 meters or standard loads. Thanks to its integrated interfaces, TCP/IP, USB, and RS232C, it is highly versatile and can be used with a wide range of different controllers. The space-saving, flat housing for DIN rail mounting makes it ideal for installation in control cabinets. Its five LEDs on the top of the housing provide the user with important information about the operating status.
