Features
ZOTECH Z920K series are able to easily wireless those messy RS485 / RS232C wires for Industrial IoT, smart building or other IoT applications.
Z920K wireless is designed with an OKI MH920 module to keep a good communiation quality. The main advantage of Z920K application is that the original control/data collect systems and sensing equipment can be kept to save cost and time for a mesh network establish.
Z920K-P/Z920K-C support Modbus RTU/ASCII , and feature a low power consumption, long-range and robust wireless mesh network.
To compare with the other wireless WiFi, ZigBee..., Z920K 920Mhz radio frequency has better capabilities of wall penetration and anti environmental interfiences.
When the communication network needs to cross floors and areas and minimun equipment changes as well as the installation should be simple and fast, Z920K wireless mesh converter will be a perfect solution for a choice.
