    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.

    Solid State Relay OutputSolid 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 AlarmingAlarm outputs can also be configured to actuate simple devices.
