Coolwell Industrial Grade Isolated Converter USB to 2CH RS485 Onboard Original FT2232HL Chip 2-CH USB to RS485 Adapter Stable and Reliable Communication
ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•USB to RS485 converter, extending USB to 2CH RS485, allows concurrent and independent communication for each channel
•USB to 2 channel RS485 converter, onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal; with 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
