[Introduction]：E90-DTU(400SL22P) is a true high-quality industrial-grade wireless digital radio. The power supply supports 3-level protection, RS485 and RS232 support 4-level protection, and the RF port supports 4-level ESD protection. It can be used in industrial applications where the electromagnetic environment is more complicated.
