Solid State Relays (SSR) are designed to provide a reliable, convenient and cost-effective method of switching electrical power from one source to another, without requiring any physical contacts between the two. The SSR family consists of several types, each of which provides a different method of switching power. One type, the D4D07L, is a commonly used relay that provides a low-cost, highly reliable switching solution.

The D4D07L is a four-pin, dual-in-line (DIL) type solid state relay (SSR) designed to switch electrical power from one AC load to another and is available in a variety of ratings, from 5A to 40A. It consists of three components: an input/output drive circuit and two power outputs. The input is connected to the source of power, and the two power outputs are connected to the two AC loads.

The D4D07L is operated by a low voltage DC signal. When the voltage applied to the input pins reaches a specified threshold (normally 8-10V), the input/output drive circuit begins to turn off the first power output and turn on the second power output. This, in turn, triggers the second output to turn off and the first output to turn on, thus switching the electrical power from one load to the other. The D4D07L is designed to switch power from either AC or DC systems.

The D4D07L is typically used in switching applications such as cars, refrigerators, air conditioners, lighting systems, industrial controllers, vending machines and other power switching applications. In addition, due to its fast response time and low-operating voltage, the D4D07L can be used in applications where noise-reduction, or where instantaneous switching is desired. The D4D07L is also common in industrial control systems, where it can be used to switch between two loads, or to control multiple loads from a single input signal.

The D4D07L provides high reliability, due to its highly rated isolation, which prevents accidental switching, and due to its built-in EMI suppression, which prevents interference with adjacent circuitry. The D4D07L is also designed for long life, with an MTBF (Mean Time Between Failures) of 8 million hours, and a maximum switching cycle rate of up to 2000 cycles /minute. The D4D07L’s power switching and control capabilities make it a great choice for a variety of applications.
