The module iSMA-B-4U4O-H has 4xUI (Universal Inputs) and 4xDO (Digital Outputs). UI can work in 5 different modes: temperature, voltage, current, resistance, dry contact. DO are relay outputs 230 V AC/30 V DC max. 3 A.
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.
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.
All universal inputs have 16-bit resolution which support the following types of inputs:
