| The SC-IF loop powered signal conditioner whose
function is to provide a 0 - 10kHz frequency output signal in
response to a 4-20mA analog input. The SC-IF appears to the input
loop as a series shunt resistor. A small sense resistor is used to
measure the input current. The input loop derives it’s power from
the input current loop.
This input current signal is then scaled and converted to a 0 to
10,000 Hz frequency signal by a Current to Frequency Converter. This
frequency signal is then transmitted across an opto-isolator to the
output stage. The 10-50 mA range option is provided to enable the
unit to perform range conversions as well as signal isolation. |
