Solid state relays (SSRs) have become increasingly popular for controlling electrical devices, and the ASSR-4118-503E model is no exception. This SSR is a 4-pole AC/DC contact type relay that offers a wide array of features that make it a great choice for applications ranging from industrial automation to home applications. In this article, we’ll take a closer look at the electrical field and working principle of the ASSR-4118-503E.

An SSR is an electronic switching device that controls an electrical load without directly switching the current. Instead, the switching process is handled by a solid state device such as a semiconductor. The ASSR-4118-503E is an AC/DC contact type SSR which actuates an AC or DC load. This SSR is designed to handle up to 10A/point at 250 volts AC/DC, and the 4 individual poles are rated for up to 5A/dc and 7.5A/ac.

The ASSR-4118-503E SSR’s application field covers a wide range of electrical control applications. It can be used for controlling pumps, fans, motors, lighting, and other electrical devices in industrial automation processes. It can also be used for home automation applications such as controlling smart lights, curtains, and other household appliances.

When it comes to working principle, the ASSR-4118-503E SSR uses an input signal to control the switching process. The input signal is either a 3-31VDC PLC ON/OFF signal or a 0-10V PLC signal depending on the application. When the input signal is detected, the SSR will switch the state of the load from off to on or vice versa. The ASSR-4118-503E also features an LED indicator that will light up when the load is activated.

The ASSR-4118-503E solid state relay is known for its high reliability and durability, making it an ideal choice for applications that require long-term, precise performance. It is designed with a non-latching contacts structure, meaning that the SSM’s operation will be reset when the power is disconnected. Additionally, the ASSR-4118-503E features built-in protections such as over-current, over-voltage, short-circuit, and others to help ensure safe operation.

The ASSR-4118-503E solid state relay is a versatile and reliable device that can be used for a variety of industrial and home application. It offers the necessary switching performance to control electrical devices, and sufficient protections to prevent any damage or malfunction. In addition, the SSR is relatively easy to operate, making it an ideal choice for a wide variety of applications.
