RS232 to RS485 Serial Port Data Interface Adapter Converter, Max 1.2KM LongDistance Serial Transmission, 3Bit Screw Terminal Block Transceiver for Industrial Control Serial Communication

This RS232 to RS485 serial interface adapter converter converts unbalanced RS232 signals into differential RS485 signals to realize longdistance serial communication. The maximum effective transmission distance can reach 1.2KM, making it wellsuited for complex onsite industrial environments where long cable runs are required.

It comes with 3bit screw terminal block for A, B and GND signal wiring. You can fasten signal wires tightly with screws to prevent poor contact caused by vibration or pulling. Pure hardware conversion solution, no driver or extra configuration required, just finish physical wiring to start data communication.

Integrated antisurge and filter circuits effectively restrain electromagnetic interference and transient voltage spikes, reducing data error rates in noisy workshop conditions. Compatible with most standard RS232 devices such as PLCs, industrial meters, serial sensors and controllers. Widely applied in equipment debugging, data acquisition, factory automation and remote monitoring projects. It is a costeffective serial conversion accessory and compatible with all mainstream brand devices with standard RS232 port.
