The module 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.
4I4O-H 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 ASCII/RTU and BACnet MSTP, which are selected using DIP switches.
