Yes, you can use it for remote (aux analog) input (RSP, AIN2, AIN4), control output (OUT, OUT2), transmission output (RET), and other things depending on the parameter settings.
The UT55A and UT52A temperature controllers employ 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 UT55A/UT52A also support open networks such as Ethernet communication.
