S89R11DBD1-12 Datasheet/PDFPower Relays, Over 2 Amps
The S89R11DBD1-12 is a power relay from Weidmuller that has an 11-pin connector configuration and switching power of 16A. It is especially designed to be used in multiple applications in both industrial and home settings.
Application Fields
The S89R11DBD1-12 has a wide variety of applications, including in the automotive, lighting (such as for LED lighting), HVAC, and security systems industries. Additionally, the relay can be used in assembling lines where automation is needed. It is also used when powering small and mid-size engines such as those used in wind turbines and generator sets.
Working Principle
The S89R11DBD1-12 is a coil-operated, non-latching relay. It has two switching states, energized and de-energized, and switches from one state to the other when a current is applied to its coil. It is usually connected in a NO, normally open, configuration, where de-energizing the coil closes the contact and energizing the coil opens it, but it can also be connected in an NC, normally closed, configuration where de-energizing the coil opens the contact and energizing it closes it.
The S89R11DBD1-12 is designed to switch a wide range of load currents, from micro-amperes up to 16 Amps. It has a low power consumption, and can withstand over-voltages of up to 400 volts. Additionally, it is designed to minimize contact bounce and reduce arcing which increases the lifespan of the contacts.
The S89R11DBD1-12 is also both vibration and shock resistant. Its housing is made of a thermoplast material that provides thermal stability, even in temperatures as low as -20°C. This makes it ideal for harsh industrial environments.
Comparison with Other Relays
The S89R11DBD1-12 has a wide variety of options for customers depending on their application requirement. Compared to other relays, the S89R11DBD1-12 provides higher switching power, from micro-amperes to 16 Amps, compared to other relay models which can range from 1 Amp to 6 Amps. Additionally, the S89R11DBD1-12 offers both a NO and an NC configuration option, which may be useful for multiple applications.
The S89R11DBD1-12 is designed to provide reliable switching and is also vibration and shock resistant. This makes it an ideal choice for applications in harsh industrial environments. Additionally, the relay is designed to provide long-term reliability and is thermally stable in temperatures as low as -20°C.
Conclusion
The S89R11DBD1-12 is a power relay with a variety of applications. It has an 11-pin connector configuration and switching power of 16A. It is vibration and shock resistant and is designed to provide reliable switching and long-term reliability.
