iSMA Controlli Mini 4I4O-H
The iSMA-B-4I4O-H has 4x DI (Digital Inputs) and 4x DO (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.
iSMA 4I4O H module has got build in 3 light control modes which allow to use the module as light application controller.
Protocols: Modbus ASCII/RTU and BACnet MSTP
Product Description
The iSMA 4I4O H module is factory-equipped with the two most popular open communication protocols: Modbus ASCII/RTU and BACnet MSTP, which are selected using DIP switches. 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.
