The H971 and EA20 use Pulse Reset Technology™ with field proven circuitry to provide a superior solution for DC applications with minimal risk of permanent magnetization, providing longer life and better accuracy. The EA20 and the H971 have 4 to 20 mA output only. The H971 also offers bi-directional sensing capability and a user-adjustable span to allow greater application flexibility. AGENCY APPROVALS Agency Approvals CE 4: EN61010-1, CAT III, Pollution Degree 2, basic insulation APPLICATIONS Note: Do not use the LED status indicators as evidence of applied voltage. 1. For currents over 120A, supply voltage must be at least 15V. 2. For H971, at zero monitored current: 35mA max.; at 200A monitored current: 55mA to 100mA depending on supply voltage and current polarity. 3. Unless factory set per customer specifications (H971SP only). 4 . The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of Conformity for additional details. 5.
