INTRODUCTION
INSTALLATION
The SC100 Signal Conditioner provides excitation and signal processing to amplify two low voltage sensor signals to
industry standard voltage and current levels for further use in process control and monitoring applications. The SC100
supports two different sensor families: fi rst, differential signal sensors such as strain gauge load cells used to measure
force or tension; second, single-ended signal sensors such as LVDT load cells used to measure force or tension and
web guide sensors used to measure web edge position.
The DIN Rail mountable SC100 features an adjustable, bipolar excitation voltage that ranges from ±5 to ±15 VDC.
Both SC100 inputs accept output voltages from sensors in a maximum range of 0-1 V. A gain range selector switch
is available for each input channel, choosing either high or low gain. Further, both 0-10 V and 4-20 mA ranges are
provided for each output and can be scaled to any desired engineering unit using onboard zero and span calibration
potentiometers. These outputs are suitable for use as a feedback signal to indicators, PLCs, PCs or other controls.
