OMIH-SS-112LM,000

Power relays, such as the OMIH-SS-112LM,000, provide a switch-like mechanism for controlling the power to an electrical load from an external source. The relays come with built in protection to prevent damage from overloads, shorts, and over-current conditions. When a power requirement necessitates higher amperage than a simple switch can provide, a power relay is often used to provide the necessary control.

Design Components

Power relays and contactors, like the OMIH-SS-112LM,000, are composed of several basic components. These include a coil, one or more contactors, an enclosure, and a pilot device or trigger switch. The relays also feature a voltage rating and a contact rating. The voltage rating is the maximum voltage the relay can handle, while the contact rating is the amperage it can support. In addition to these components, the OMIH-SS-112LM,000 features metal oxide varistors (MOVs) to help protect the contacts against any potential over-current or surge conditions.

Operation

The OMIH-SS-112LM,000 is an electronic power relay designed for applications using up to 2 amps of current. The relay operates by using an electromagnetic coil to move the contactor, which physically opens and closes the contacts. When an appropriate voltage is applied to the coil, it activates the contactor, which then completes the circuit. When the coil is deactivated, a spring returns the contactor to the off position. This allows for switching between two different power sources.

Safety Features

The OMIH-SS-112LM,000 features several protection methods. In addition to the internal MOVs, the relay has a bimetallic strip which acts as a heat sink when there is an overload condition. When the strip reaches a certain temperature, it interrupts the power to the coil, turning off the relay. It also features a diode which prevents a re-strike when the coil is energized, eliminating the chance of a spark or an arc.

Applications

The OMIH-SS-112LM,000 is designed for applications with a maximum of 2 amps of current. It is suitable for applications such as HVAC, lighting, motor control, vending machines, and small power tools. Its robust design and safety features make it a popular choice for industrial and commercial applications.

Conclusion

The OMIH-SS-112LM,000 is a high-quality power relay designed for applications up to 2 amps of current. Its compact size and robust design make it a reliable solution for many industrial and commercial applications. Its features include MOVs, a bimetallic strip, and a diode for safe operation.
