Trip amplifier for monitoring AC/DC circuits – Overview
Trip amplifier for monitoring AC/DC circuits
Monitoring AC/DC currents and voltages within
single-phase and three-phase power networks.
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.
