Siemens Time Delay Relay 24V DC

The Siemens Time Delay Relay 24V DC is an electronic timer relay designed for delayed switching applications in industrial control, motor control, and process automation. Siemens offers models such as the 3RP15 series with a control supply voltage option of 24V DC and others that can work with 24 to 240V AC/DC. These relays provide versatile time ranges, for example from 0.05 seconds up to 100 hours, with high accuracy (setting accuracy < ±5% and repeat accuracy < ±1%).

Key features include:

• Various timer functions like ON delay, OFF delay, ON+OFF delay, cyclic timing, pulse shaping, and more, configurable via rotary switches.

• Compact design with a slim 22.5 mm or 45 mm width housing suitable for DIN rail mounting.

• High mechanical endurance with up to 30 million operations.

• Surge suppression to protect electronic circuits.

• Clear status indication with LEDs for control supply and relay switching.

• Rated operational currents typically up to 3A AC or 1A DC with contact configurations such as SPDT.

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