The Yokogawa UD1AG3-050N-1KD-2TA-N/CN is a highly configurable Single-Input Signal Conditioner from the Yokogawa UTAdvanced series.
This "smart" DIN-rail mounted conditioner is designed for critical process applications. It provides electrical isolation, signal conversion, linearization, and alarm functionality for a single field instrument signal. The complex suffix code defines its precise configuration: it is set up to accept a K-type thermocouple (T/C) input, convert it into an isolated 4-20 mA analog output, and provide two built-in alarm relays. The /CN suffix indicates this unit is intended for the Chinese market, often implying specific documentation or conformity.
