  • Page 7: Signal Input, Module Me Overview

    SIGNAL INPUT, module ME OVERVIEW This module together with the "MP" input board, performs the signal conditioning (see Fig. 2). This module contains the trimmers and jumpers for the amplifier gain and the low level output (offset). The signal input connections are made at Terminals 3, 4, 5 and 6. FIG.7 OFFSET ADJUST Solder pad 1 if closed : Adjust the low range level of the output (Offset positive coarse).
  • Page 8: General Specifications

    CCT-80, ELECTRICAL FEATURES This signal conditioner provides connection to 4- or 6-wire strain-gages (load-cells), which provide a nominal of 2 mV/V or 3 mV/V output with 350 Section. The signal conditioner does not provides the bridge excitation voltage, therefore is necessary to use an external auxiliary power supply.
  • Page 9: Signal Input Range Selection
