DCSA SERIES
Description
The DCSA Series is a loop-powered, linear output current
transducer that provides an output that is directly proportional to
the RMS AC current passing through the LCSC10T12 sensor. The
DCSA Series provides either an analog current or voltage: 4-20
mA, 1 to 5VDC, or 2 to 10VDC. Each unit is factory calibrated
for monitoring (with the LCSC10T12 connected) in one of four
ranges; 0-5, 0-10, 0-20, or 0-50A. Zero and span adjustments
allow field calibration if needed. The DCSA Series mounts on
both DIN 1 and DIN 3 rails.
Operation
The DCSA Series varies the effective resistance of its output
in direct proportion to the current flowing in the conductor
monitored by the LCSC10T12. Connecting the power supply to
terminals C & D provides a 4 to 20mA DC current. Connect the
power supply to terminals C & A to get 1 to 5VDC at terminal D.
Connect the power supply to terminals C & B to get 2 to 10VDC
at terminal D.
