Transducers designed for the measurement of generator
field currents (used with a shunt). The input is designed
for 50mV or 75mV shunts and has an isolation rating
of 3500 VDC. Standard output is either ±10VDC (model
FCT-01-10V) or 420mA (model FCT-01-420m). Housed in
a fiberglass box with watertight fittings for cable
entry and exit.
Specifications
FCT-01-10V Output:
±10VDC
FCT-01-420m Output:
4-20mA
bipolar: -75mV in:4mA out, 0mV in:12mA out,
75mV in:20mA out
unipolar: 0mV in:4mA out, 75mV in:20mA out
Bandwidth:
-3dB @ 1500Hz
Gain:
Adjustable: typically set to 133.3 which yields
10VDC out for a 0.075V input from a standard 75mV
shunt.
Gain Drift:
25 ppm/°C max
Isolation:
Uses a 3 port isolation amplifier (input, output
and power supply) with ±3500 VDC isolation
between any two ports.
