Features at a glance:
- Onboard SP3232EEN and SP485EEN chips. Fast communication, stable and reliable, better compatibility
- Stable transmission at the rate of 300~921600bps
- Onboard unibody power supply isolation, provides stable isolated voltage, and needs no extra power supply for the isolated terminal
- Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
- Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock proof performance
- Onboard 15KV ESD isolation protection and 600W lightning proof & anti-surge protection
- Onboard 120R terminal resistor on the RS485/RS422 interface, disabled by default, configurable by jumper
- The onboard power supply screw terminal, allows 5V~36V DC wide-range input
- 3 LEDs for indicating the power and transceiver status
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
