Your advantages:

• All versions have removable terminals

• Many versions are available with innovative

spring-loaded terminals

• All devices have electrical isolation

Exception: 24 V AC/DC

• Simple handling using a rotary potentiometer

• Selectable hysteresis

• For devices with two threshold values, the operating

principle can be selected

Applications:

• Protecting motors and equipment/systems

• Monitoring temperatures in electrical cabinets

• Frost monitoring

• Temperature limits for process quantities – e.g. in the

packaging industry or galvanizing systems

• Controlling plants and machines such as HVAC systems,

solar collectors, heat pumps or warm water supply

systems

• Monitoring oil in bearings and gearboxes

• Monitoring cooling liquids

3RS10/11 relays are used to measure tempera-

tures in solid, liquid and gaseous mediums. The

temperature is measured using a sensor that is

in the medium, evaluated by the unit and moni-

tored to determine whether the temperature is

within the upper and lower temperature limits.

Depending on the function that has been pa-

rameterized, the output relay either switches on

or off at these threshold values.
