Rice Lake SCT-30 Signal Conditioning Transmitter Analog Output RS-485 DIN Rail

The Rice Lake SCT-30 Signal Conditioning Transmitter is a compact, DIN-rail mountable digital weight transmitter designed to convert load cell signals into reliable analog outputs for industrial weighing and automation applications. Ideal for control panels, process control systems, hopper monitoring, batching operations, and PLC integration, the SCT-30 delivers high-precision signal conditioning with simple setup and dependable performance.

Featuring an integrated LCD display, digital rotary controls, and diagnostic functions, the SCT-30 allows operators to easily perform calibration, zero, tare, and setpoint adjustments without complex programming. The transmitter supports up to eight 350-ohm load cells and utilizes a high-speed 24-bit A/D converter to ensure accurate signal processing and exceptional measurement stability.

The SCT-30 provides multiple selectable 16-bit analog output options, including 0-20 mA, 4-20 mA, 0-5 VDC, 0-10 VDC, ±5 VDC, and ±10 VDC, making it compatible with a wide range of industrial automation and control systems. An RS-485 communication port enables reliable serial communication for integration into modern process environments.

Designed for harsh industrial settings, the unit includes diagnostic monitoring for load cell disconnects and over-capacity conditions, helping reduce downtime and simplify troubleshooting. Its compact footprint allows easy installation on standard Omega/DIN rails within electrical cabinets and junction boxes.
