Power Relays, Over 2 Amps

The PCLH-204D1S is an industrial power relay that is designed and used in a wide variety of applications where a high-power switching mechanism is required. It consists of two main components – a power relay and a secondary relay.

The Power Relay

The primary function of the power relay is to activate an electrical switch when the voltage voltage of the current being delivered meets a specified level. This can be used to control the operation of an HVAC system or any other high-power application. The primary relay is rated to handle up to 2 amps of current, making it suitable for most high-power applications.

The Secondary Relay

The secondary relay is used to ensure that the contactors do not activate any higher than the predefined voltage. This secondary feature is particularly useful if the current draw is expected to exceed the threshold for the primary relay. The secondary relay is controlled by an external circuit and is rated for up to 3.2 amperes.

The Working Principle

The PCLH-204D1S operates on a simple principle. When the voltage of the current meets the pre-defined threshold, the secondary relay activates and the power relay is then activated, causing the contacts to close and allowing electricity to flow through the circuit. When the current drops back below the pre-defined threshold, the secondary relay deactivates and the power relay opens, causing the contacts to open again and stopping the flow of electricity.

Applications

Power relays are used in a wide range of applications including HVAC systems, lighting systems, motor control systems, and any other high power applications. These relays can also be used in industrial applications as they are rated up to two amperes, making them suitable for most industrial applications. Thus, the PCLH-204D1S is a versatile and reliable power relay and is well suited for a variety of industrial applications.
