Up to 4. Even with a contact output addition option, parameters are only available for setting up to 4 alarms. If you require a 5th or additional alarms, you can create an alarm function on the UT55A in a ladder program. Note that the LL50A parameter setting software (sold separately) is required to use the ladder program function.
The UT35A and UT32A 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 UT35A/UT32A also support open networks such as Ethernet communication.
