The module has 4xUI (Universal Inputs) and 4xAO (Analog Outputs). UI can work in 5 different modes: temperature, voltage, current, resistance, dry contact. AO are 0-10 V DC with max. 20 mA load allow direct control of relays (12 V DC) or SSR with PWM support.
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 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.
