AC/DC Rotor Current Monitor ES-IS30R
or AC/DC Current monitor, Rotor current monitor, AC/DC Current relay, AC/DC Current sensor, Rotor current relay
- Current relay for monitoring the rotor current circuits of collector ring rotor induction motors
- Rated current range: 0.5 ... 600AW (ampere windings), f = 0...110Hz
- Suitable for monitoring the currents of frequency converters
- Fault memory and indication for each phase
- Delayed activation of the fault signallings (adjustable from 0 ... 3.8 sec.)
- Fault signallings via 2 relays (1 changer each) and 3 optocoupler output per phase
