Rice Lake SCT-40 Signal Conditioning Transmitter – Multi-Channel DIN Rail Weight

The Rice Lake SCT-40 Signal Conditioning Transmitter is a high-performance digital weight transmitter designed for industrial weighing, process control, and PLC integration applications. Featuring support for up to eight independent load cell channels, the SCT-40 provides accurate signal conditioning and reliable communication in a compact DIN-rail mounted package.

Engineered for seamless integration into automation systems, the SCT-40 converts load cell signals into analog, serial, or fieldbus outputs while providing advanced calibration and diagnostic capabilities. The backlit graphic LCD display allows operators to monitor weight, calibration settings, configuration parameters, and system error conditions directly from the transmitter.

The SCT-40 supports multiple communication options including RS-485, RS-232, Modbus RTU, DeviceNet®, PROFIBUS®, EtherNet/IP™, PROFINET, and Modbus TCP, making it an ideal solution for manufacturing, material handling, batching, tank weighing, and process control applications.

Designed for industrial environments, the SCT-40 includes digital inputs and outputs, theoretical and real-weight calibration functions, push-button or preset tare operation, and advanced diagnostics for enhanced system reliability and performance.
