Product description

The WK107A works as a repeater for RS485 with galvanic isolation. WK107B is an interface converter from RS232 to RS485. The device is designed for RS485 half-duplex operation. The device is fully set via the DIP switches and is immediately ready for operation. The WK107A is simply snapped onto a top-hat rail for installation.

Technical data

Input / output K107A:

RS485 <> RS485 half-duplex

Connection:
