Description
Description
Isolated asynchronous bidirectional RS232 to RS485 converter in industrial quality. Embedded TVS (Transient Voltage Suppressor) and lightning-proof diodes.
Features
- Compatible with RS232/RS485 standard, converting RS232 signal to a symmetrical differential RS485 signal
- Stable transmission at speeds ranging from 300 to 115200 bps
- Integrated isolation of the unibody power supply provides stable isolated voltage, requiring no additional power supply for the isolated terminal
- Integrated unibody ADI magnetic isolation enables signal isolation, high reliability, strong anti-interference, and low power consumption
- Onboard TVS (Transient Voltage Suppressor) effectively suppresses surge voltages and transient peak voltages in the circuit, lightning-proof, and antistatic
- Onboard resettable fuses and protection diodes ensure current/voltage-stable outputs, providing overcurrent/overvoltage protection and enhancing shock resistance
- Integrates optional 120-ohm resistor for RS485 output port, activated/deactivated via a switch
- DC-005 socket allows for a 6V to 36V DC wide input range, suitable for various application scenarios
- 3x LED indicators for easy status checks: Power, Transmit, and Receive
- Aluminum alloy housing with sandblasting and anodizing, solid and durable
