The TR-4 is a microprocessor-based transmitter designed to process load cell signals for industrial applications. It serves as a signal converter for PLCs or similar industrial control devices in weighing, batching, level control, and process control systems. With a user-settable relay output, it can manage stand-alone automation tasks such as on-off switching and filling/emptying operations. Its rail-mounting design ensures seamless integration with other panel components and simplifies wiring.

Built for demanding industrial environments, the TR-4 features three-way galvanic isolation. This protects load cells from damage caused by leakage currents and ensures output stability remains unaffected by electrical noise. All configurations are handled via tactile keys, eliminating the calibration drifts associated with traditional potentiometric components.
