SCT-40 Signal Conditioning Transmitter

General information

Compact Control

Designed for PLC systems that require seamless integration of weight data, the SCT-40 provides reliable signal-conditioning function without the cost or bulk of a full size weight indicator/controller. With eight independent load cell channels, the SCT-40 delivers more power and more control in a compact design.

The versatile SCT-40 is DIN-rail mountable within a cabinet or control panel, where it converts a scale’s load cell signal to analog output, serial output or a fieldbus protocol. Providing more interface surface than its predecessors, the SCT-40 is more technician-friendly and easier to use, which simplifies scale setup, calibration and operation.
