FEATURES
•Package : mod. DIL-14
•A magnetic sensor chip (employing the
magnetoresistive effect of thin film permalloy)
measures the magnetic field generated by an
internal current-carrying conductor
•measurable direct or alternating current IM up to
20A
•supply voltage 12 V
•no auxiliary field HX required
•it’s possible to overload the conductor (between
pin’s 8,9,10 and 11,12,13) with 300A for 10 ms
at Tamb = 20 °C
package : modified DIL-14
1, 2, 7: not connected 3: +VO 4: -VB 5: -VO 6: +VB 8, 9, 10: current output 11, 12, 13: current input
VO - output voltage VB - supply voltage
