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 Output


For 1/32 DIN Panel Cutout Size	For 1/16 DIN Panel Cutout Size	For 1/8 DIN Panel Cutout Size

For 3/16 DIN Panel Cutout Size	For 1/4 DIN Panel Cutout Size

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.

Washdown Autotuning Temperature Controllers

The faceplate on these controllers is sealed to meet NEMA 4X and IP66 for protection in washdown environments with splashing water, corrosive liquid, and dust. The rear case meets IP20, which prevents objects about the size of a finger from coming into contact with a live circuit.

Because they have proportional-integral-derivative (PID) software, these controllers are ideal for turning heating equipment on and off in systems with rapid, unpredictable, and complex temperature changes. They help you achieve precise and stable temperature control with fuzzy logic that learns system behavior and automatically compensates for changes. Use the autotuning function to cycle and identify the ideal PID variables for your system to achieve the most precise control. These controllers read temperature with a highly sensitive thermocouple probe (sold separately) in critical process applications. All fit into instrument panels with DIN cutouts. Use the keypad to adjust the actuation point, reset point, and other settings.

For 1/8 DIN Panel Cutout Size	For 1/4 DIN Panel Cutout Size

Mechanical relay outputs actuate circuits directly.

SPDT—Single pole, double throw (SPDT) relays can be set to turn the circuit from off to on (normally open) or from on to off (normally closed).

SPST-NO—Single pole, single throw (SPST) relays turn one circuit from off to on (normally open).

Automatic Reset—Controllers with automatic reset switch off and on again automatically as the temperature fluctuates.

Manual Reset—Controllers with automatic/manual reset give you the choice to have machines turn back on either automatically when the temperature fluctuates, or you can manually reset their switch. When set to manual they shut down your machine when it gets too hot to protect equipment and personnel. They won’t turn the machine back on until you reset their switch. They have a second output to actuate an alarm or another simple device.

DIN-Rail-Mount Autotuning Temperature Controllers

Mount these temperature controllers directly onto DIN rail for controlling 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. 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 or RTD probe (both not included) 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.

All meet American, Canadian, and European safety standards.

Mechanical Relay Output

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 and For Cooling—Those with cooling/alarm outputs can also be used to turn cooling equipment on or off at a specified temperature.

For Alarming—Alarm outputs can be configured to actuate alarms or other simple devices.
