Solid state relays (SSRs) are devices that use a semiconductor switching element such as a transistor or a thyristor to control an electrical circuit. The CKRA4820R is a solid state relay manufactured by the Crystal Alarm Systems (CAS) Corporation that can be used in industrial, commercial, or residential applications.

The CKRA4820R solid state relay features advanced switching technology, which allows for efficient operation and support for a variety of switching applications. It can interface with an existing system or be used to control a new system. It is designed to be used in typical PLC (programmable logic controller) applications, and can control loads of up to 10A at up to 250VAC or 30VDC. The CKRA4820R solid state relay has a wide operating temperature range of -40°C to +85°C and is UL-approved for UL508 compliance.

In addition to the CKRA4820R solid state relay, CAS Corporation also manufactures a range of other relays, such as indicator relays, surge protection relays, and motor protection relays. The CKRA4820R can be used in hazardous locations, such as Class I, Division 2 and other areas. The relay is ideal for a variety of industrial processes, including motor control and process control, as well as other applications that require high reliability and a long service life.

The working principle of the CKRA4820R solid state relay is very simple. It has two sets of electrical contacts. The control (input) contacts are the ones that are connected to an external signal source such as a PLC. When the external signal is applied to the control contacts, it causes the core of the relay to switch, closing the power (output) contacts, which in turn, controls the load. The contacts remain closed while the external signal is applied, and open when the signal is removed.

The CKRA4820R solid state relay is highly reliable and efficient, and can be used for applications in a wide range of industries, including automotive, HVAC, home automation, and security. Its small size makes it ideal for use in confined spaces and it allows for easy installation.

The CKRA4820R solid state relay is a great choice for applications that require reliability and long service life. Its advanced switching technology makes it a perfect fit for applications that require precise control. With its wide operating temperature range and UL-approval for UL508 compliance, it is a reliable and cost effective choice for commercial, industrial, and residential applications.
