    Autotuning Temperature Controllers

    Ideal in systems with rapid, unpredictable, or complex temperature changes, these controllers turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control. They work similarly to proportional controllers but gather more variables to calculate the most effective way to return to the target temperature and avoid overshooting. They also have fuzzy logic to learn your system's behavior and compensate as needed. Use the autotuning function to have the controller cycle and identify the ideal PID variables for your system. You can also manually select the PID variables. These controllers read temperature with a highly sensitive thermocouple or RTD probe (both not included) in critical process applications. Since they reset automatically, they switch off and on again as the temperature fluctuates. All fit into instrument panels with DIN cutouts. Use the keypad to adjust the actuation point, reset point, other settings.
    All meet American, Canadian, and European safety standards.

    Mechanical relay outputs actuate circuits directly. All are single pole, single throw (SPST) relays and turn one circuit from off to on (normally open).
    For Alarming—Alarm outputs can also be configured to actuate simple devices.
    IP20 Enclosure Rating and IP50 Enclosure Rating—IP20 rated controllers prevent objects about the size of a finger from coming into contact with a live circuit. IP50 rated controllers protect against dust.

    Solid state relay outputs send a pulse signal to directly control an external solid state relay (not included). They have a longer service life than mechanical and signal relays. Use them for more precise and rapid control switching than mechanical relays.
    For Alarming—Alarm outputs can also be configured to actuate simple devices.

    Bench-Top Autotuning Temperature Controllers

    Built into an enclosure, these temperature controllers are protected when sitting on your workbench. Ideal in systems with rapid, unpredictable, or complex temperature changes, they turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control. All work similarly to proportional controllers but gather more variables to calculate the most effective way to return to the target temperature and avoid overshooting it. They also have fuzzy logic to learn your system's behavior and compensate as needed. Use the autotuning function to have the controller cycle and identify the ideal PID variables for your system. These controllers read temperature with a highly sensitive thermocouple probe in critical process applications. Since they reset automatically, they switch off and on again as the temperature fluctuates. Use the keypad to adjust the actuation point, reset point, and other settings.
    The controllers have mechanical relay outputs that actuate circuits directly. All are single pole, single throw (SPST-NO) relays and turn one circuit from off to on (normally open).

    Controllers with high-limit control let you attach a second thermocouple probe to take the temperature of your heating equipment. If your equipment reaches the high limit, these controllers shut down your heating equipment and won't let it turn back on until you manually reset it, improving the safety of your system.
