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.
