E810-U41 USB to RS485 serial port to RS232 converter Industrial grade TTL conversion module communication adapter photoelectric isolation RS422 high protection protection industrial lightning protection 3M high speed [Chip solution]：FT4232H [Operating voltage]：DC 4.5~5.5V [Product size]： 120*72*34mm [Introduction]：E810-U41 is an industrial-grade USB to 4-way RS485 conversion module. With an external USB interface, 4 independent RS485 interfaces can be converted without affecting each other. It is suitable for scenarios where the computer is connected to multiple RS485 networks at the same time. Built-in RS485 automatic transceiver switching circuit, independent pin control switching, makes RS485 communication more reliable, and can connect more devices at the same time.
