$40.70
Siemens 3RA2815-1AW10 solid-state time-delayed auxiliary switch, off delayed, without control signal, relay: 1 CO, time range 0.05-100 s, 24-240 V AC/DC, 50/60 Hz, varistor for attenuation of the contactor coils integrated, screw terminal, can be snapped onto the front on contactors 3RT20 and contactor relays 3RH2
Overview
The Siemens 3RA2815-1AW10 is a high-performance, solid-state time-delayed auxiliary switch designed for seamless integration with SIRIUS 3RT2 contactors and 3RH2 contactor relays. This component is a crucial element for implementing precise, time-controlled functions in industrial control systems.
Engineered for off-delayed operation without an auxiliary control signal, it provides reliable timing from 0.05 to 100 seconds. The wide-voltage operating range of 24-240 V AC/DC ensures maximum flexibility and reduced inventory across different global applications. Featuring a 1 CO (Changeover) relay contact and screw terminals for secure wiring, the 3RA2815-1AW10 simplifies complex control wiring while enhancing system reliability.
Key Benefit
- Simplified Installation: The snap-on front mounting onto 3RT20 contactors and 3RH2 contactor relays saves space and significantly reduces wiring time, minimizing potential installation errors.
- Enhanced Reliability: Integrated varistor for attenuation of the contactor coils provides surge suppression, protecting your contactors and extending their operational life.
- High Precision Timing: The solid-state electronic design delivers excellent repeat accuracy across a wide, adjustable time range of 0.05 to 100 seconds.
- Universal Application: Its multi-voltage capability (24-240 V AC/DC, 50/60 Hz) makes it globally compatible and versatile for a variety of industrial automation projects.
Application
The Siemens 3RA2815-1AW10 is perfectly suited for control circuits requiring a reliable delay after the contactor is de-energized, such as:
- Fan Overrun Control: Keeping a cooling fan running after the motor has stopped.
- Solenoid Valve Control: Ensuring a valve stays open for a set duration to complete a process cycle.
- Sequence Timing: Implementing timed sequences and interlocking functions in machinery.
