Product Description
2 In 1 DB9 Female RS232 to RS485 TTL Converter
PCM-KW-473 is an active RS232 to RS485 TTL converter designed to interface equipment using a DB9 female RS232 port with RS485 or TTL serial connections. The front end uses a D Sub 9 Pin female connector for RS232 input, while the opposite side provides a 5 position terminal block with 3.81 mm pitch for field wiring.
The terminal interface exposes RS485 A/B differential signals, GND, and TTL RXD/TXD connections, enabling bidirectional serial signal conversion between compatible interfaces. An Active LED provides operating status indication. The integrated 4-40 mounting hardware supports panel installation, while the mechanical design allows front rivet nut or rear locking screw mounting configurations.
