PM485REP - RS232/RS485 to RS485 Isolated Repeater

The PM485REP unit is a bi-direction isolated serial repeater unit used to convert 2 wire RS485 twisted pair (or 3 wire RS232) data communications signals to another isolated 2 wire RS485 twisted pair cable. The unit is fully configurable via DIP switches for baud rate, parity, data bits and stop bits. The repeater can be used to extend a RS485 network up to a further 1000 metres. The isolation also prevents ground loops between different parts of the network.

The PM485REP is the ideal unit to use for isolating Promux modules housed in an electrical panel from long RS485 networks which could suffer from ground loop problems.

The PM485REP can also be used as a RS232 to RS485 isolated converter.
