Features:
1. Onboard original FT232RL and SP485EEN chips; fast communication speed, stable and reliable, better compatibility
2. On-board integrated power isolation, providing stable isolation voltage, no additional power supply is required at the isolation end
3. Onboard integrated digital isolation, signal isolation, high reliability, strong anti-interference, low power consumption
4. Onboard TVS (Transient Voltage Suppressor), effectively suppressing surge voltage and transient peak voltage in the circuit, lightning protection and anti-static
5. On-board self-recovery fuse and protection diode to ensure stable current/voltage output, provide over-current/over-voltage protection, and improve impact resistance
6. Onboard 15KV ESD isolation protection and 600W lightning surge protection
7. The RS485/RS422 interface has a 120R terminal resistor on board, which is enabled by default and can be configured by jumpers
8. 3 LEDs to indicate power and transceiver status
9. Industrial-grade rail-type ABS shell design, small size, easy installation, high cost performance
