Siemens Time Delay Relay 12V DC

Siemens Time Delay Relay 12V DC is a type of electronic timer relay used in control, starting, and protective circuits to manage time delays in switching operations. It belongs to the Siemens SIRIUS 3RP25 series and features a compact, space-saving design suitable for mounting on DIN rails, commonly used in industrial control panels and switchgear.

Key features and description:

• Operates on a supply voltage range from 12V up to 240V AC/DC, including 12V DC models.

• Time delay ranges typically configurable, for example, from 1 to 20 seconds or wider ranges depending on model.

• The relay can have single or multiple contacts (e.g., DPST configuration with 2 contacts).

• It includes a time range selector switch and LED indicators for operational status.

• The design allows easy installation with cage clamp terminals and DIN rail mounting.

• Common applications include star-delta motor starting and protective timed operations.

• Maximum current capacity around 3 Amps and maximum voltage around 240V AC/DC.

• Operating temperature range typically from -25°C to +60°C.
