Signal relays are electrical components that are used to switch electrical circuits off and on. These special relays are used for low-power switching applications and are typically rated for up to two amperes (2A). The HC4ED-PL-AC6V is a signal relay product that meets this particular rating requirement.

The HC4ED-PL-AC6V signal relays come in a single-pole/double-throw configuration with a maximum voltage rating of 250V AC/DC. The relays are made with UL approved materials and have an operating temperature range of between -40° and +85°C. The HC4ED-PL-AC6V relay itself is relatively small at a mere 12.15 mm in length and 10.2 mm in width. It also has two LED indicators (ON and OFF/TRIPPED) that provide feedback on the state of the connection.

Using the HC4ED-PL-AC6V signal relay in applications where two amperes of power is needed can be beneficial for two primary reasons. The first is that it is extremely small, making it easier to mount and fit into tight electrical connections. The second reason is the LED indicators, which provide clear feedback that the relay is either on or off. This can help to prevent electrical damage that may occur from either an initialization failure or power loss when switching between different circuit states.

The working principle of the HC4ED-PL-AC6V signal relays involves the use of a pair of coils and an electrical contact system. When an electrical current is run through the coil, it activates the contact system and closes the circuit. This allows electrical current to flow from one circuit to the other. When the coil current is stopped, the contact system opens the circuit again, and no further electrical current can pass.

The HC4ED-PL-AC6V signal relays can be used in a variety of applications, including industrial, automotive, and home uses. These relays are perfect for controlling small loads, such as alarm systems, small motors, and other small-scale appliances. Thanks to their small size, LED feedback, and low power rating of up to two amperes, these relays are an excellent choice for applications where space is at a premium and accurate switching is an absolute necessity.
