Yokogawa Temperature Transmitter
Yokogawa Temperature Controller UT55A
General
The Yokogawa Temperature Controller UT55A employs an easy-to-read, 14-segment large color LCD display, along with navigation keys, thus greatly increasing the monitoring and operating capabilities. A ladder sequence function is included as standard. The short depth of the controller helps save instrument panel space. The Yokogawa Temperature Controller UT55A also supports open networks such as Ethernet communication.

*1: When “1” or “6” is specified for the Type 2 code, only “0” can be specified for the Type 3 code.
*2: When the /LP option is specified, the RS-485 communication for “1” or “2” of the Type 2 code is 2-wire system.
*3: When any of “1”, “2”, “4”, “5”, or “7” is specified for the Type 2 code, the /DR option can be specified.
*4: The /LP option can be specified in the combination of Type 2 code (any of “0”, “2”, “3”, or “4”) and Type 3 code (any of “0” or “1”). Additionally the /LP option can
be
specified in the combination of Type 2 code “1” and Type 3 code “0”.
