Yokogawa YTA70 Temperature Transmitter
Description
Like the YTA50, the YTA70 is a 2-wire analog temperature transmitter that outputs a simple 4 to 20 mA output that correspondes to the temperature measured. However, it adds HART® 5 (Code -E) or selectable HART® 5 or HART® 7 (Code -J) digital communication.
The YTA70 delivers all the benefits found in the YTA50 while adding HART® digital protocol communication. The HART® protocol allows you to conveniently configue the transmitter using the latest FDT/DTM technology. The YTA70 is the choice for all your control applications.
The YTA70 is a head mount type of temperature transmitter that accepts thermocouple, RTD, ohms or DC milivolts input and converts it to a 4 to 20 mA DC signal for transmission. The YTA70 conforms to the standard DIN form B head mounting. The YTA70 supports HART® communication protocol.HART protocol revision is selectable from HART 5 orHART 7, and HART 7 features long tag number up to 32 characters, enhanced burst mode and eventnotification, and command aggregation function.
