MicroStep-MIS
Matrix is an array of signal relays capable of switching 45 four-wire channels or 15 twelve-wire channels. It is designed to calibrate multiple electronic sensors such as RTD thermometers, electronic barometers, hygrometers, anemometers etc.

Thanks to signal relays the signal passing through Matrix is undisturbed, unmodified and it is suitable for both - analog and digital lines such as UART, SDI-12, RS-232, RS-485 etc.

Matrix is controlled by simple commands transmitted via RS-232 interface. It works well with MicroStep-MIS CalibLab software for calibration and adjustment automation.

Removable connectors, which can adopt pigtail wires up to 1.5 mm2 (16 AWG) can be easily used for each channel.

Life cycle of relays reliably last up to 100 million cycles. Contact resistance is bellow 200 mOhm throughout the whole life.
