Industrial Grade Isolated RS232 TO RS485 Converter, ADI Magnetical Isolation, 600W Lightningproof & Anti-Surge Industrial RS232 TO RS485 Converter Industrial Grade Isolated RS232 TO RS485 Asynchronous Bi-Directional Converter Embedded TVS (Transient Voltage Suppressor) And Lightningproof Diodes ![](https://www.waveshare.com/img/devkit/accBoard/RS232-TO-RS485/RS232-TO-RS485-details-1.jpg) Features At A Glance - Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal
- Stable transmission on rate of 300~115200bps
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock resistance
- Integrates optional RS485 output terminal 120R resistor, enabled/disabled via switch
- DC-005 power jack, allows 6V~36V DC wide range input, suits different application situations
- 3x LED indicators, easy to check the operating status: power, transmitting, and receiving
- Aluminium alloy enclosure with sand blasting and anodic oxidation, solid and durable
