More about selecting SIRIUS 3RS relays

Equipment temperature monitoring

The relay evaluates whether the temperature exceeds or falls below the set limits. The supported sensor type, measuring range, number of thresholds and output contacts vary by model.

Relay selection and replacement

Compare the full order number, supply voltage, sensor type and wiring, and the set limits. Resistance sensors and different thermocouple types cannot be interchanged without checking the settings and wiring.

Send the full order number or a photo of the nameplate, the required quantity and, for repairs, a fault description. We will check the relay version, spare-part availability and diagnostic and repair options. Faulty parts are sent to FOXON for repair.
