This device uses the original FT4232HL chip for fast, stable, and reliable communication, with excellent compatibility. It supports USB connections to four isolated RS232 channels, enabling easy expansion for industrial serial devices. The design includes a built-in power supply isolation for stable voltage and digital isolation for high reliability and low power consumption. To protect against voltage surges and spikes, it features an onboard Transient Voltage Suppressor. It also includes a self-recovery fuse and protection diodes to ensure stable current and voltage with over-current and over-voltage protection. The power supply can be input through a screw terminal, supporting a range from 5V to 36V DC. Additionally, there are nine LEDs to indicate power and transceiver status, all encased in a durable aluminum alloy enclosure with a sandblasted and anodized finish.
