K-Box
INF2201
K-Box Multi-DAQ Modules aid in measuring Thermocouples, Voltages, Currents and PWM. These include our unique power down and WakeOnCAN feature and can be stacked with all of our K-series instrumentation modules.
K-Box transmits the Data periodically on the CAN Bus for accurate sensor measurement.
