YTA320 Field Mount Temperature Transmitter
Brand: Yokogawa Electric CorporationThe YTA320 is the highly accurate temperature transmitters that accept Thermocouple, RTD, ohms or DC milivolts inputs and converts it to a 4-20 mA DC signal for transmission.
The YTA320 is a dual input model. The models support either BRAIN or HART communication protocol, and YTA320 also supports FOUNDATION fieldbus.
The YTA320 in their standard configuration, with the exception of the Fieldbus type, are certified by TÜV as complying with SIL 2 for safety requirement.
