UD1A-050N-1KD-2SA-2/PHC/CE

The Yokogawa YTA410/430 is a high-performance, microprocessor-based two-wire temperature transmitter. It is designed to receive a signal from various types of thermocouples (TC) or resistance thermometers (RTD), convert it into a standardized 4 to 20 mA DC analog output signal, and transmit it to a control system.
