Mini 8I-IP

The module has 8xDI (Digital Inputs). DI can work as dry contact or fast pulse counter up to 100 Hz save in EEPROM memory.

The module is factory-equipped with the two most popular open communication protocols: Modbus TCP/IP and BACnet IP, which are selected using DIP switches.

Built-in Modbus Gateway TCP/IP to Modbus ASCII/RTU, enabling you to connect additional modules/devices that communicate via Modbus RS485.

Addressing the modules is via rotary switches, which facilitates and accelerates the process of commissioning the system.

Built-in mini USB allows for initial configuration of the unit without power supply.
