DB9 Male RS232 Breakout Board Solderless Screw Terminal Module with Housing & Long Mounting Bolts, 9Pin D-SUB Serial Adapter

This DB9 male breakout module converts standard 9-pin RS232 D-SUB signals to independent screw terminals, enabling convenient signal splitting, wiring modification and equipment fault diagnosis without soldering operations.

Each terminal corresponds to a marked DB9 pin, allowing quick wire connection, disassembly and replacement for frequent wiring adjustments in labs or on-site industrial maintenance. The matched full protective housing wraps the circuit board to isolate exposed metal contacts and avoid accidental short circuits caused by debris or collision.

Supplied with dedicated long mounting bolts, the breakout board can be firmly fixed to equipment cabinets, control boxes and test benches. It supports standard RS232 serial communication, widely compatible with industrial controllers, frequency converters, barcode scanners and various serial testing instruments. Compact integrated structure saves installation space and extends service life under long-term continuous working conditions.
