DB9 RS232 Breakout Terminal Block Module with Housing, Solder-Free D-SUB Female Serial Port to Wiring Terminal Breakout Board Adapter

This DB9 RS232 breakout board is designed to convert standard D-SUB 9Pin female serial port to screw terminal wiring, featuring a solder-free structure that eliminates complex soldering work for rapid circuit wiring.

Each pin corresponds to an independent screw terminal with clear printed pin number labels, allowing users to fasten signal and power wires securely by tightening screws. The matched plastic protective shell fully wraps the circuit board, preventing accidental short circuits caused by metal contact and blocking dust to extend service life in industrial environments.

It complies with standard RS232 serial communication protocol and delivers stable serial signal transmission, widely used for industrial PLC debugging, data acquisition sensors, serial monitoring modules, POS equipment and serial communication host wiring projects. No auxiliary power or driver software is needed; simply connect wires to terminals and plug serial devices into the DB9 female port for instant communication.

Compact size saves installation space on control boxes and chassis panels, an ideal maintenance and wiring accessory for automation equipment, electronic debugging and serial signal conversion scenarios.
