Adopts original FT2232HL chip, fast communication, stable and reliable, better compatibility Extending USB to 2CH RS485, allows concurrent and independent communication for each channel; Onboard unibody power supply isolation, provides stable isolated voltage, 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 suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic; Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance; Built-in 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching.
3 LEDs for indicating the power and transceiver status; Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
