Fully automatic transceiver circuit with no delay, ensures fast and stable communication between the USB port and different interfaces, without interfering with each other. 9 LEDs for indicating the power and transceiver status. High quality USB-B connectors, smoothly plug/pull. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance. 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. Supports USB to 4-ch multi-functional serial port, convenient for expanding or debugging various industrial serial port devices. Supports USB to 2-ch isolated RS485/RS422 + 2-ch isolated RS485. Industrial USB to 4-ch RS485/422 Converter adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility. Industrial grade metal case, supports wall-mount and rail-mount installation, solid and beautiful, easy to install.
