Control Relays

SIRIUS Function Relays, Interfaces & Converters @ Siemens

SIRIUS Contro Relays Family

The SIRIUS family of relays offers solutions for monitoring, switching and timing applications, and for the conversion of analog signals

Monitoring relays have a solution for you, whether it's temperature, voltage, current, speed or level. Simple configuration and selectable input sensors make these units a snap to implement.

Switching relays provide solutions in the forms of compact housing and DIN rail mounting, while also being able to accommodate high current switching capacities.

Timing relays offer flexible input voltages and selectable time ranges. Their versatility often allows a single unit to match most industrial applications.


Interface converters are used for the conversion of analog signals from field devices to match control system signal levels. SIRIUS interface converters offer a compact size and convenient DIN rail mounting with selectable input and output ranges. Manual override switches allow manual adjustment of the output signal, making these products ideal for analog signal simulation.


Plug-in Relays come in basic and premium styles in a wide current range to ensure a solution for every application.  Optional accessories include LEDs, mechanical flag indicators, push-to-test buttons, and latching hold down doors.
