27830: RS232 to RS485 converter, Active Digital Isolator, DIN rail support, Protection from Lightning and Surge up to 600W, Multi-Isolation Protection, LED Indicators

The RS232 to RS485 converter from Waveshare is an industrial module designed to convert an RS232 signal into a balanced differential RS485 signal, ensuring reliable serial communication even in environments with strong electrical interference. Thanks to the integrated active digital isolation and multiple protections against surges and electrostatic discharge, it is particularly suitable for industrial, agricultural and IoT applications where signal safety and stability are essential. DIN rail mounting makes installation in electrical panels easier, allowing you to place multiple modules side by side with ease.

## Technical Specifications

- Compatible with RS232/RS485, converts the RS232 signal into a balanced and differential RS485 signal.
- Stable transmission speed with a frequency range from 300 to 115200 bps.
- Integrated power isolation (unibody) provides a stable isolation voltage without the need for external power for the isolated terminal.
- Integrated digital isolation (unibody) ensures signal isolation with high reliability, strong interference immunity, and low energy consumption.
- Integrated TVS (Transient Voltage Suppressor) effectively suppresses mains surges and transient voltage spikes in the circuit, offering protection against lightning and electrostatic discharge (ESD).
- Automatic reset fuse and integrated protection diodes ensure a stable current and voltage output, protection against overcurrent and overvoltage, improving resistance to electrical shock.
- Integrated 120Ω RS485 termination resistor, switchable on/off via a jumper (jumper pin).
- Integrated screw terminal for power supply supports a wide input voltage range from 5V to 36V DC.
- Industrial-grade eco-friendly ABS enclosure, compact size, easy to install and cost-effective.
