The ISC300 is an isolated measurement channel with open circuit sensor detection for use with RTD and thermocouple temperature sensors. In addition to temperature measurement, the ISC300 can accept full scale input voltages of ±100mV and ±10V which allows use with other sensors such as pressure, humidity and flow sensors. The low level resistance measurement capability also allows stimulus and measurement of strain gauges. The measurement channel has a highly stable internal reference which can be selected from the output side. This allows the user to calibrate each channel at the factory, record the calibration data and periodically recalibrate the system while in use over time and ambient temperature changes.
