Is the UT-2017 converter with photoelectric isolation a WiFi module?

UT-2017 converter with photoelectric isolation is not a WiFi module. It is an RS232 to RS485 converter, used to convert single-ended RS-232 signals into balanced differential RS-485 signals, and has a built-in optical isolator to provide voltage isolation. This is different from the WiFi module, which is a device used to realize LAN connection or Internet access. It usually has the function of converting data from the serial port, USB interface or Ethernet interface into wireless signals.

The functions of UT-2017 RS-232 to RS-485 smart protocol converter are:

1. Convert single-ended RS-232 signal to balanced differential RS-485 signal.
2. The built-in photoelectric isolator can provide isolation voltage up to 2500Vrms, with a fast transient voltage suppression protector. This protector is designed to protect the RS-485 interface.
3. Using today’s advanced TVS transient voltage suppressor, the TVS tube is in a high-resistance state under normal circumstances. When both ends of the TVS tube experience an instantaneous high-energy impact, the impedance at both ends of the TVS tube can be reduced at an extremely high speed. It absorbs a large current, thereby clamping the voltage at both ends at a predetermined value, and protecting subsequent circuit components from damage due to transient high voltage shocks.
