Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space. Use to regulate line-voltage HVAC systems where flammable gases, vapors, and dust are present. Thermostats are rated Class I, Divisions 1 and 2, Group D; and Class II, Divisions 1 and 2, Groups E, F, and G.

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 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.

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 are auto/manual selectable.

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. 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). Single pole, single throw (SPST) 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.
