12V 4-Channel DB9 RS232 Relay Board for Remote Control and Serial Port Switching
This RS232 relay board enables remote control of motors, lights, and industrial devices through UART serial communication. It solves the need for automated switching in automotive and industrial applications where direct human intervention is impractical
Connect the DB9 interface to your computer or controller using a serial cable. Send simple text instruction ("open", "close", "read") via terminal software to activate relays individually or in interlock mode. The low standby current (18mA) ensures minimal power drain during continuous run, making it suitable for vehicle installations
