The Yokogawa UT35A-001-11-00 is a Signal Conditioner / Isolator designed for use with RTD (Resistance Temperature Detector) sensors, specifically Pt100.
Its primary function is to accept the weak and noise-sensitive resistance signal from an RTD, electrically isolate it from the source to prevent ground loops and noise interference, convert it into a robust, standardized analog output signal (such as 4-20 mA), and transmit this signal to a PLC, DCS, or other control/monitoring system.
