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). Solid state relay drive 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. Analog signal outputs are typically used with SRC (silicon controlled rectifier) power controllers (not included) for some of the highest precision control.

Alarm outputs can also be configured to actuate simple devices.

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.

DIN-rail/surface-mount adapters (sold separately) mount 1/16 DIN controllers to a DIN rail or surface.

DIN cutout adapters (sold separately) convert larger cutouts to fit 1/16 DIN controllers.

Washdown Autotuning Temperature Controllers

1/4 DIN

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.

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

Mechanical relay outputs actuate circuits directly. Single pole, single throw (SPST) relays turn one circuit from off to on (normally open). 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).

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.

Analog signal outputs send 4-20 mA current to actuate equipment on a current loop. They are typically used with SRC (silicon controlled rectifier) power controllers (not included) for some of the highest precision control.

DIN-rail/surface-mount adapters (sold separately) mount 1/16 DIN controllers to a surface.

DIN cutout adapters (sold separately) convert larger cutouts to fit 1/16 DIN controllers.

Mechanical relay outputs actuate circuits directly. All are single pole, single throw (SPST) relays and turn one circuit from off to on (normally open). Solid state relay outputs send a pulse signal to directly control an external solid state relay (not included). They last longer than mechanical and analog signal relays.

Analog signal outputs are typically used with SRC (silicon controlled rectifier) power controllers (not included) for some of the highest precision control.

Alarm outputs can be configured to actuate alarms or other simple devices. Those with cooling/alarm outputs can also be used to turn cooling equipment on or off at a specified temperature.
