YTA110 Temperature Transmitter

Mar 31, 2016

YTA110 Temperature Transmitter

 

The YTA110 is the high performance temperature transmitter that accepts Thermocouple, RTD, ohms or DC milivolts inputs and converts it to a 4 to 20 mA DC signal for transmission. The YTA110 supports either BRAIN or HART communication protocol. The YTA110 in it standard configuration is certified by TU ¨ V as complying with SIL2 for safety requirement.

 

FUNCTIONAL SPECIFICATIONS

Input

Input type is selectable: Thermocouples, 2-, 3-, and 4-wire RTDs, ohms and DC milivolts. See Table 1.
on page 3.

Span & Range Limits

See Table 1. on page 3.

Input signal source resistance (for T/C, mV) 1 k or lower

Input lead wire resistance (for RTD, ohm) 10  per wire or lower

Output

Two wire 4 to 20 mA DC. Output range: 3.68 mA to 20.8 mA

BRAIN or HART ® protocol is superimposed on the 4 to 20 mA signal.

Any single value from the followings can be selected as the analog output signal.

Sensor 1, Terminal Temperature.

Also, up to three of the above values can be displayed on LCD display or read via communication. 

Isolation

Input/Output/GND isolated to 500 V DC
