The adaptable Microlink 851 features 32 frequency counting and event counting, digital inputs and outputs, and an extensive range of analogue measurements including strain, flow, pressure, voltage, current, temperature, pH and level - although extra modules may be needed for some types of sensor.

The Microlink 840 is ideally suited for monitoring analogue transducers including pressure, temperature, force, voltage and current, monitoring digital sensors like flow meters; counting switch closures; counting items produced; monitoring machines to record percentage on/off times and logging data from utility meters.
