UOTEK TTL to RS-485 3.3V Module RS485 Anti-surge Protection Isolation Voltage 1000VDC UT-M3485
UT-M3485 series isolation transceiver module integrated with power isolation, electric isolation, RS-485, and interface chipset, which is
isolation and BUS protection in one. It is convenient to embed into the device, so as to get RS-485 connect function. This series is using
dosing technology, with great isolation function. The isolated voltage can be as high as 1,000V DC. It can be used in industrial communication, coal mine industry, power security, building automation, Petro/chemistry, PLC, and transducer.
