44A0211-8-8

Model 44A0211-8-8 is a type of electromechanical relay manufactured by Controlotron Corporation. It is a two-stage, low-power latching relay used primarily in low-voltage, low-current applications. This relay is suitable for many switching and controlling applications, including motor control, security systems, lighting, metering and HVAC systems.

The 44A0211-8-8 comprises two relays in a single unit, each of which can be set separately. The first relay is a latching relay and the second one is an auxiliary relay. The latching relay is used to activate and deactivate the circuit, while the auxiliary relay is used for indicating the relay state. The latching relay is actuated by applying a short pulse of current or voltage to the coil; the relays remain in their respective positions until reset by another pulse. The latching relay has a holding current of 0.05A and a maximum current rating of 250V AC or 30V DC.

The 44A0211-8-8 is also equipped with an optional coil reset circuit, allowing the relays to be reset by applying a separate signal to any of the relay contacts. This allows the user to reset the relays from any point in the circuit, which is especially useful in applications that require the resetting of remote components. In addition, the relay can be triggered by an external signal, such as a timing pulse, allowing the user to coordinate multiple relays.

The 44A0211-8-8 also has an anti-bounce circuit, which helps to minimize contact bounce, which can lead to unwanted current spikes in sensitive applications. This feature is especially useful for controlling the speed of motors, as it ensures a smooth transition when switching on and off.

The 44A0211-8-8 is a versatile and affordable solution for applications that require reliable switching and control capabilities. The relays are designed to be resistant to environmental factors and have a long operating life, making them ideal for long-term usage in industrial, commercial, and military applications.

Overall, the 44A0211-8-8 is widely used in many different types of applications due to its reliable switching and control capabilities, robust design and affordable price tag. As a result, many home automation projects and professional-grade systems are using this type of relay, and it is highly recommended in such applications.
