UD1AG3-200N-1KD-2SA-N/CN

Yokogawa Temperature Transmitter (YTA Series), Model: UD1AG3-200N-1KD-2SA-N/CN
This is a head-mounted, two-wire temperature transmitter from Yokogawa's YTA series. It is designed to accept a Thermocouple (Type K) sensor input and convert it into a standardized 4-20 mA analog output signal proportional to the measured temperature, incorporating HART® 7 protocol for digital communication and configuration.
