  • Page 7: Product Overview

    CONTENTS Product overview The DLCA NET-S1 is a DIN rail-mounted digital load cell amplifier that provides excitation voltage for load cells, measures the returned force signal, and then converts this signal into a digital value that represents tension and analog output signals. The tension is displayed on the DLCA NET-S1 device.

  • Page 8: Additional Tools

    CONTENTS Product overview continued The DLCA NET-S1 has three alarm outputs. Two of the alarm outputs can be configured to sense tension limits on either of the two sensor inputs. The third alarm output is on when there are no load cell wiring problems detected or power faults. This is essentially a 'power good' indicator.
