H971 Bi-Directional DC Current Transducers
The H971 transducers are split-core DC current sensing transducers that measure bi-directional (positive and negative) DC currents and output a 4-20mA signal. As the parts are bi-directional, 12mA output corresponds to 0 Adc, 4mA corresponds to negative full scale current and 20mA corresponds to postive full scale current. The H971 has a field adjustable current range allowing users to set full scale ranges from +/-20Adc to +/-200Adc.
The H971SP is identical to the H971 but has been factory calibrated for the user specified full scale range.
Transducers require 12 to 24Vdc power (for current sensing greater than 120Adc, 15Vdc minimum supply voltage is required) Nominal power supply current draw is less than 100mA.
