The SCT-20 Signal Conditioning Transmitter from Rice Lake Weighing Systems delivers a compact, space-saving solution for digital-to-analog weight conversion in industrial settings. Designed to be DIN-rail mounted, its vertical footprint saves control panel space, making it ideal for applications with limited real estate.
The SCT-20 features multiple calibration methods, including theoretical, real-weigh, and linearity calibration, allowing for quick setup and precise results. A six-digit LED display provides constant visibility into weight, configuration settings, calibration status, and error conditions.
Designed for seamless system integration, the SCT-20 supports ASCII and MODBUS-RTU protocols and offers optional fieldbus communication through DeviceNet™, Profibus™, and EtherNet/IP™ outputs. It powers up to eight 350-ohm load cells, while the opto-isolated analog output ensures clean, interference-free signal transmission.
Built-in bit swapping allows compatibility with big or little endian format systems. It also features two digital inputs and three outputs to meet advanced industrial control requirements. Whether you're managing complex process controls or basic signal transmission, the SCT-20 provides the flexibility and reliability required for high-performance weighing systems.
