Product catalog summary

Device Features

Control via USB and power supply through USB or external DC.
Includes RFID reader for charging authorization.
Equipped with 11 RGB LEDs for visual status indication and a buzzer for acoustic signals.
Features a relay output, integrated WiFi module, and two USB host outputs.
Contains ambient light and temperature sensors.

Intended Use

The HMI module is designed for user interaction with Bender charge controllers in EV charging stations. It connects via USB and should only be used with compatible Bender charge controllers.

Product Description

The module enhances charge controllers by adding sensors, actuators, and communication interfaces, facilitating user interaction.

Functional Description
