The iReact-EXT-1 unit is a smart sensor, providing extension of analog and digital measurements of the iReact-3 automation controllers. The iReact-EXT-1 provides an analog input suitable for interfacing the voltage measurement coil of the primary high voltage of the substation’s transformer, as well as the frequency of the power network. In addition, it measures the substation’s battery. It provides two independent 4…20mA analog inputs, as well as four (4) digital inputs, both useful for interfacing extra signals and substation’s systems. The sensor is able to digitally configure and independently calibrate all analog inputs, using a host computer interfaced via USB. The iReact-EXT-1 has built-in power supply, supporting 36-115VDC power input.
