Enclosure Thermostats



Control a single heating or cooling device in your enclosure to keep electronics at a safe operating temperature. Clip them on to a DIN rail and connect them to your heater, fan, or air conditioner.
All these thermostats meet American, Canadian, or European safety standards. They have an IP20 rating—to prevent shocks, fingers won’t fit inside. They also meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.
Adjustable thermostats let you set the temperature you need. Nonadjustable thermostats have a fixed temperature setting to prevent tampering or accidental changes.
These thermostats keep the air in your enclosure within a set range. Temperature setting is the high end of the range for both heating and cooling thermostats. Heating thermostats are normally closed—when the air in your enclosure reaches the temperature setting, the thermostat will turn the heater off. Cooling thermostats are normally open, so they’ll switch your fan or air conditioner on when the air in your enclosure reaches the temperature setting.
Temperature difference is the difference between the temperature when the thermostat turns your device on and when it turns off. For a heater thermostat with a temperature setting of 50° and an 18° temperature difference, the thermostat will switch your heater on when the temperature goes below 32° and off once the temperature reaches 50°. Thermostats with a lower temperature difference maintain a narrower range of temperatures, but they use more power because they switch on and off more frequently.

Enclosure Thermostats for Multiple Devices



Keep electronics in your enclosure from getting too hot or cold with these thermostats that control two devices at once. Clip them to a DIN rail to install.
Nonadjustable thermostats prevent tampering and accidental changes. Adjustable thermostats allow you to set custom temperatures.
Heating and cooling thermostats control heaters and fans or air conditioners. Thermostats with one actuation point, also known as changeover thermostats, switch between heating and cooling so one device is always running. When the temperature in your enclosure gets hotter than the temperature you set, the thermostat will turn on your fan or air conditioner. It goes back to heating once the temperature is reduced by the temperature difference. So for a thermostat with a temperature difference of 9° F, setting it at 60° F means it will heat the enclosure until it reaches 60° F, switch to cooling until it reaches 51° F, and then switch back to heating.
Heating and cooling thermostats with two actuation points control two devices independently. When your enclosure temperature is within the set range, neither device is powered, so they’re more efficient than changeover thermostats. For each device, temperature setting is the high end of the temperature range, and temperature difference is the size of the range. For a thermostat with temperature settings of 59° and 95° F and an 18° F temperature difference, the heater will switch on when your enclosure is colder than 41° F and turn off when it reaches 59° F. The fan or other cooling device will switch on when the temperature goes above 95° F and turn off once the enclosure cools to 77° F.
Cooling thermostats regulate two cooling devices, such as a fan and an air conditioner, for two-stage cooling. Use only one device for cooling in mild temperatures or both for extreme heat. These thermostats switch your equipment on when the enclosure is hotter than the temperature setting. Once the temperature is reduced by the temperature difference, it will switch off. For example, a thermostat set at 77° F for a fan and 140° F for an air conditioner will power both devices when the enclosure is over 140° F. With a temperature difference of 18° F, the air conditioner will switch off when the temperature goes below 122° F. The fan will run until the temperature reaches 59° F, and switch back on if it heats up to 77° F or hotter.
All thermostats meet IP20, which means they’re designed so fingers can’t fit inside and get shocked. They also meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch on fire and won’t spread the fire by dripping. Thermostats that are CE marked or VDE certified meet European safety standards. UL Recognized Component and C-UL Recognized Component thermostats also meet American and Canadian safety standards.

Enclosure Climate Sensors


These sensors measure temperature and humidity, then send that information to your PLC or controller to regulate heating and cooling equipment, alarms, and data recorders. Choose a sensor that works with your digital IO-Link or analog 4-20 mA system. Clip it to a DIN rail or screw it in to your enclosure, and use the micro M12 plug to connect the sensor to your controller.
Sensors meet American, Canadian, and European safety standards. Rated IP20, they’re designed so fingers can’t reach the electrical parts inside and get shocked. They also meet UL 94 V-0, so if they catch fire, they’ll self-extinguish within 10 seconds and won’t spread the fire by dripping.

Autocorrecting Washdown Precision Panel-Mount Temperature Controllers




The faceplate 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. These controllers have proportional-integral-derivative (PID) software with fuzzy logic that learns system behavior and automatically compensates for changes to achieve high accuracy in applications with fluctuating conditions. They read temperature with a highly sensitive thermocouple probe (sold separately) in critical process applications to turn heating equipment on or off at a specified temperature. All fit into instrument panels with DIN cutouts. Set actuation points with the keypad.
Controllers with automatic reset turn machines back on once the temperature decreases. Controllers with automatic/manual reset give you the choice to have machines turn back on either when the temperature drops or you reset their switch.
Controllers with 1/16 DIN trade size have one alarm relay.
Controllers with 1/8 and 1/4 DIN trade size have two alarm relays.
Mechanical relays actuate one circuit directly. SPDT (Single pole, double throw) relays can be set to turn the circuit from off to on (normally open) or from on to off (normally closed). SPST (Single pole, single throw) relay turns the circuit from off to on (normally open).
Solid-state relays actuate an external relay (not included). They have a longer service life than mechanical or signal relays.
Signal relays output 4-20 mA current to actuate equipment on a current loop.

Precision Panel-Mount Temperature Controllers

Install these controllers into instrument panels. They read temperature with a highly sensitive thermocouple or RTD probe (sold separately) in critical process applications to turn heating equipment on or off at a specified temperature. Set the actuation point with the keypad. Controllers are SPDT (single pole, double throw). They can be set to turn one circuit from off to on (normally open) or on to off (normally closed).

High-Limit Precision Panel-Mount Temperature Controllers


To protect equipment and personnel, these controllers shut down your machine when it gets too hot and won’t let it turn back on until they’re reset. Mount them to DIN panel cutouts in your heating equipment. You can reset them by hand or remotely so long as the sensor is below the set temperature. These controllers require a thermocouple (sold separately) to read temperature and have a single primary output to turn heating equipment on or off at a specified temperature. They have one or two mechanical relays that are single pole, double throw (SPDT). This means each relay turns a circuit from off to on (normally open) or from on to off (normally closed). All controllers meet American, Canadian, and European safety standards.
To mount 1/16 DIN controllers to a surface or DIN rail, add DIN-rail/surface-mount adapters. To convert larger cutouts to fit 1/16 DIN controllers, add DIN cutout adapters.

Panel-Mount Temperature Controllers
Install these controllers in DIN panel cutouts to maintain your heating equipment’s temperature. When your machine gets too hot, they turn it on and off in short cycles to cool it down. Use them on electric heaters only—they won’t work with valves or solenoids. These controllers require a Type J thermocouple probe (sold separately) to read temperature. They have a mechanical relay that is single pole, double throw (SPDT), meaning it turns one circuit from off to on (normally open) or from on to off (normally closed). All controllers meet American, Canadian, and European safety standards.
To mount 1/16 DIN controllers to a surface or DIN rail, add DIN-rail/surface-mount adapters. To convert larger cutouts to fit 1/16 DIN controllers, add DIN cutout adapters.
