DCP485-P

The DCP485-P is a fully isolated DIN Rail RS-232 to RS-485 Converter offers a complete electrical isolation barrier and heavy duty electrical surge protectors. Isolation is provided by optical couplers and a transformer isolated DC-to-DC converter. The RS-232 connection is through male or female EIA 9-pin D-sub connectors or a 3-wire RS-232 connection can be made through convenient pluggable screw terminals. The RS-485 connections are made through convenient pluggable solder-less screw terminals. The device is designed for full duplex operation over two wire pairs. Outputs are tri-state, allowing multi-dropping of up to 32 units over one pair. The RS-232 interface includes request to send (RTS) and data terminal ready (DTR) either of which can be used via DIP switches to enable the RS-485 transmitter.
