Signal Relays, Up to 2 Amps: 3SBC1683A2 Application Field and Working Principle

3SBC1683A2 is a compact and reliable signal relay especially designed for SPDT (single pole double throw) switching applications. It features two separate contacts which can be operated simultaneously or independently. This type of signal relay is ideal for controlling and monitoring low power current or voltage switching applications, such as those found in alarm systems, sensors, and self-testing equipment.

The 3SBC1683A2 operates in two modes – the input terminals being active or passive. In active mode, both contacts are actuated by a signal from an external source (DC voltage or current). In passive mode, the relay is actuated by an external voltage applied to its terminals. The relay\'s contacts open or close depending on the polarity of the applied voltage.

Features

The 3SBC1683A2 has a maximum contact current of 2 A, and a maximum voltage of 200 VDC (maximum coil operating voltage is 24 VDC). It can switch various AC and DC loads and is suitable for a wide range of switching applications. It also features a selection of accessories including snubber, bracket, and mounting hardware.

The 3SBC1683A2 is a fast, silent and reliable signal relay with a low profile. Its compact design is ideal for applications requiring small footprints, and its convenience makes it easy to install with minimal effort. Its low profile design can also save space and reduce clutter.

Applications

The 3SBC1683A2 is a popular choice for switching applications in industries such as automotive, home and building automation, industrial automation, consumer electronics, energy management, and robotics. Its capabilities are especially useful in alarm and security systems, instrumentation, home automation, HVAC systems, and industrial automation.

This signal relay is also commonly used in numerous embedded applications, such as controllers, peripherals, and system boards. 3SBC1683A2 is renowned for its ability to switch AC and DC loads reliably in a wide variety of applications.

Working Principle

The 3SBC1683A2 signal relay works by utilising electro-magnetic force to move a contactor within the relay. When voltage is applied to the small electromagnetic coil of the relay, the magnetic field created causes the contactor to move and thus moves the switch points, causing the circuit to be opened or closed. Thus, the relay is able to take a low voltage or current signal from the driving source as an input, and, on the basis of this signal, deliver a much higher voltage or current to the driven device.

The contactor is a spring-loaded device which ensures that the contact return to their original state as soon as the driving voltage is removed. This way, the output is always the same state as the input.

The 3SBC1683A2 also comes with an LED that shows the system status. This LED is usually located in the front and indicates when the relay is ready to switch.

Conclusion

The 3SBC1683A2 is an incredibly efficient and reliable signal relay. Its dual operation enables it to switch both AC and DC loads and its compact design can fit virtually anywhere. Its wide range of applications and low operating voltage make it a popular choice for controlling and monitoring low power applications such as alarm systems, sensors, and self-testing equipment. All in all, the 3SBC1683A2 is a versatile signal relay ideal for a range of low-power switching applications.
