HMI Wi-FI/MODBUS MODULE

The HMI module is a plug&play device that can communicate by modbus industrial protocol and set as master module. The device has a Wi-Fi/Bluetooth interface for wireless communication and can be set MQTT protocol, TCP/IP, websocket etc upon request. The device can communicate with PLC and Input/Output modules by two RS485 ports. Furthermore there is a NTC thermo sensor and can host a CO2 sensor by UART interface. The voltage supply of the current loop can be set internally or externally by 24 V power supply. The module is powered by the famous STM32F100 serie and the firmware can be customized upon request. It has high protection solutions to electrical shocks due to the specific architecture. The module comes in 3 versions, with 503 case, case for consumer application and no case. The cases can be purchased separately.

Applications
