DB9 Female Screw Terminal to RS232/RS485 Conversion Board

The DB9 Female Screw Terminal to RS232/RS485 Conversion Board is a simple yet essential adapter that breaks out all 9 pins of a standard DB9 female connector into easy-to-use screw terminal blocks. Instead of soldering wires directly to a DB9 connector, this board allows quick and secure wire connections using a screwdriver — making it perfect for industrial installations, field debugging, and prototype development. All signal lines are clearly numbered and labeled for easy identification. The board uses all-copper terminals for anti-oxidation and reliable long-term contact.
