# Analog Input Module
The Analog Input Module is used to receive data from analog devices with a -50…+50 V signal, RS-485 interface and Wireless connection is used for communication with the module. For example: a valve, a sensor and others. The Analog Input Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.

The ENP-AI4-50V Module must be horizontally mounted on 35 mm DIN rail according to IEC 60715.
# Connection Example
1 Amp Circuit Breaker recommended to use on power line for the ENP-AI4-50V Module.
Wi-Fi protocols – 802.11 b/g/n/e/i (802.11n up to 150 Mbit/s).
Bluetooth protocols – Bluetooth v4.2 BR/EDR and BLE specification.
Alternating current voltage of 110 - 220 V is potentially lethal!
All works on assembly and installation should be performed only with a disconnected power supply!
The installation and assembly of electrical equipment must be carried out by electrically qualified persons.
