Industrial RS232 to RS485 Converter

It is an RS232 and RS485 asynchronous bidirectional converter with electromagnet isolation. Built-in TVS bi-directional transient suppression diode to protect the device from unstable operation.

*Compatible with RS232 / RS485 standard, provides balanced RS232 signal Converts to differential RS485 signal
*Built-in ADI magnetic isolation provides signal isolation, high reliability, strong anti-interference, low power consumption

*Built-in TVS (Transient Voltage Suppressor) effectively suppresses overvoltage and transient surge voltage in the circuit, lightning proof and anti-electrostatic

*Built-in resettable fuse and protection diodes provide current/voltage stable outputs, provide overcurrent/overvoltage protection, increase shock resistance

*Activated via switch / disabled optional RS485 output terminal integrates 120R resistor

*DC-005 power input allows 6V ~ 36V DC wide range input, suitable for different application occasions

*3x LED indicator, easy to check the working status: power, sending and receiving
