YTA70P Panel Mount Temperature Transmitter

Brand: Yokogawa Electric Corporation

The YTA70P is a Panel mount type of temperature transmitter that accepts thermocouples, RTDs, ohms or DC millivolts input and converts it to a 4-20 mA DC signal for transmission. 

The YTA70P conforms to the standard DIN rail mounting. The YTA70P supports HART communication protocol. 

HART protocol revision is HART 7, and it features long tag number up to 32 characters, enhanced burst mode and event notification, and command aggregation function.
