Signal Relays, Up to 2 Amps

1-1617038-3 is a single-pole normally open (SPNO) signal relay manufactured by Omron. These relays are available in several package sizes from 4 to 8 pins, and are ideal for applications needing up to 2 Amp current switching. With a maximum contact load of 10A, they come with a coil voltage range of 5 to 24 VDC for added flexibility and are also UL recognition, CSA, TUV, and RoHS compliant.

Application Field

1-1617038-3 signal relays can be used in a variety of applications, including security systems, alarms, audio systems, LED lighting, and energy saving devices. They are also suitable for interfacing between two circuits with different voltage levels, thus making the 1-1617038-3 perfectly suitable for industrial automation and motor control systems. These relays provide added protection and safety features to a system while keeping the cost down.

Working Principle

The 1-1617038-3 is a SPNO relay, which means it is a single-pole, normally open switch. When the coil is energized, the relay’s contact closes and the voltage is transferred to the relay’s load. When the coil is de-energized, the contact opens, breaking the circuit. A SPNO relay features a movable contact arm that is held in the open position by the force of a magnetic field generated by an electric coil. When the coil is energized, the magnetic field generated by it attracts the contact arm, thus closing the switch and allowing electricity to flow through the circuit. The 1-1617038-3 features a simple on/off control operation and is highly resistant to temperature and shock. It is also designed with multiple safety features, such as an automatic opening fail-safe operation that prevents contact arcing if the coil voltage should suddenly drop.

Features and Benefits

The 1-1617038-3 signal relays offer several features and benefits that make them ideal for any application. For starters, they are highly reliable, since they feature Omron’s patented AgSnO2 contact material which provides high stability in contact resistances, even under severe vibration and temperature changes. In addition, they are cost-effective, due to their low energy consumption and cost-effective disposable packing.They also feature power saving and environmental protection features, such as a lower operating temperature and improved resistance to dust and humidity. This helps to reduce power consumption and the risk of system malfunctions.Moreover, they are easy to use, since they feature a quick connect terminal and no soldering iron required for quick and easy installation. The relays are also UL certified, meaning they have been tested for safety and conformance.

Conclusion

The 1-1617038-3 signal relays from Omron are ideal for any application seeking a high-quality, cost-effective solution for current switching with up to 2 Amp current limit. Their features and benefits make them highly reliable, energy efficient, and easy to use, making them the perfect solution for any application.
