Features
1) Onboard SP3232EEN and SP485EEN chips. Fast communication, stable and reliable, better compatibility
2) Stable transmission at the rate of 300~921600bps
3) Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
4) Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
5) Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
6) Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
7) Onboard 15KV ESD isolation protection and 600W lightningproof & anti-surge protection
8) Onboard 120R terminal resistor on the RS485/RS422 interface, disable by default, configurable by jumper
9) Onboard power supply screw terminal, allows 5V~36V DC wide range input
10) 3 LEDs for indicating the power and transceiver status
