Kubler standard signal controllers additionally boast 2 limit value alarms, which operate when the measured value exceeds or drops below the limit setpoint, or alternatively within a fixed band. Thanks to features such as start delay, hysteresis function and averaging, they can be employed in the most diverse applications. They can also be used as simple ON/OFF controllers. The optional analog output or serial interface enable the retransmission of the measured values to higher-level systems or monitoring devices. A totalizer function sums the measured value with respect to time, in order to measure quantities or volume over a fixed time period.
