The iSMA B 4U4O 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.
The iSMA 4U4O H 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.
4x Universal Inputs (4UI)
All universal inputs have 16-bit resolution which support the following types of inputs:
