Want to use Raspberry Pi 4 for industrial application that requires RS485/422 communication? This is a great solution for you.
Uses original FT232RNL and SP485EEN chip, with built-in galvanic isolation, lightning-proof and anti-electrostatic protection, suitable for your industrial projects.
The circuit provides isolated power and signal of the device to improve the stability of the system and reduce power consumption.
Onboard TVS (Transient Voltage Suppressor), effectively suppresses 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, provide over-current/over-voltage proof, and improve shock resistance.
The USB signal can be converted into a balanced differential RS485/422 signal. The transmission distance is about 1.2km for RS485/422 and about 5 Meters for USB.
