Mini 414O-H-IP

The module has 4xDI (Digital Inputs) and 4xDO (Digital Outputs). DI can work as dry contact or fast pulse counter up to 100 Hz save in EEPROM memory. DO are relay outputs 230 V AC/30 V DC max. 3 A.

4I4O-H-IP module has got build in 3 light control modes which allow to use the module as light application controller.

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 done via rotary switches, which facilitates and accelerates the process of commissioning the system.

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