General Specifications YTA0, YTA0 Temperature Transmitter [Style: S] The YTA0 and YTA0 are the highly accurate temperature transmitters that accept Thermocouple, RTD, ohms or DC milivolts inputs and converts it to a to 0 ma DC signal for transmission. The YTA0 is a single sensor input model, and the YTA0 is a dual input model. Both models support either BRAIN or HART communication protocol, and YTA0 also supports FOUNDATION fieldbus TM. The YTA0/0 in their standard configuration, with the exception of the Fieldbus type, are certified by TÜV as complying with SIL for safety requirement. For the specifications of Fieldbus communication type marked with, refer to GS 0C0T0-00EN. FEATURES Outstanding performance Microprocesser-based sensing technology ensures high accuracy and reliability. High reliability Dual-compartment housing realizes high resistance capability to harsh environments and the YTA0/0 have SIL capability for safety requirement. Variety of sensor inputs The type of sensor input is user-selectable from thermocouples (T/C), RTDs, ohms, or DC milivolts. Digital communication BRAIN or HART communication protocol is available. The insturment configuration can be changed by the user with using the BT00 or HART communicator. Self-diagnostics function Continuous self-diagnostics capability ensures longterm performance and lower cost of ownership. LCD display with bargraph The LCD display provides both a digital readout and percent bargraph simultaneously. Dual universal inputs (Model YTA0) The YTA0 can accept two thermocouple, RTD, ohm or DC milivolt inputs. Differential or average temperature measurement is selectable. The sensor backup function for automatically switches-over from the primary to the backup upon sensor failure.
