Yokogawa UT750-50-S4 Digital Indicating Controller

The Yokogawa UT750-50-S4 Digital Indicating Controller is a panel-mount PID controller designed to monitor and regulate process variables in industrial control systems for stable, accurate operation. It accepts universal input (thermocouple, RTD, or analog) and provides a digital PV/SV display. Output options are model dependent and may include relay, voltage pulse, or current. Power is supplied from 100–240 VAC, and the unit supports multi-alarm capability with RS-485 communication in model-dependent configurations. Common replacements include Yokogawa UT55A, UT75A, and UT35A. It is commonly used in manufacturing lines, process equipment, and automated production systems where maintenance teams and system integrators perform repair, retrofit, expansion, or replacement to maintain performance.
