Some WAVESERIES products provide the function of monitoring voltage and current. Typical uses include low voltage distribution applications. This includes the monitoring of phase voltages and current while controlling actuators. Another application is in monitoring dropouts of a power supply, or accumulators and feed-in systems within industrial production lines. There are many applications for threshold monitoring (trip amplifier) products in process automation. Typically they are used to generate alarms when „out-of-limits“ signals are detected with fill levels, flow quantities or temperature signals. E The PLUGCONTROL series of current monitoring products monitor DC current up to 10 amps. They can be used in applications to monitor the functioning of valves, servocontrols and DC motors. The pluggable detector uses the same socket (base) as Weidmüller PLUGSERIES relays and optos socket base so it uses the same quick-and-easy to use pluggable ZQV cross-connections for saving wiring time. A lever is provided to quickly release or instal the detector.
