Solid State Relays

ASSR-1219-301E is a type of solid state relay, a type of switching device achieved with the use of electronics instead of electromechanical components such as relays. It is an electrical connector device that switches on an electrical circuit and features a small control offset to switch on the relay.

Application field

Solid state relays have a wide range of applications, such as controlling lighting, temperature regulation, and monitoring voltage and current signals, as well as providing protection from electrical noise. Specific applications for the ASSR-1219-301E include:

• Lighting: The relay can be used to switch on and off lighting fixtures.
• Temperature regulation: It can be used to switch on and off heating/cooling systems in order to regulate temperature.
• Monitoring voltage and current signals: With its accurate offset, the relay can be used to monitor and detect minor changes in voltage and current signals.
• Protection from electrical noise: The solid state relay can be used to minimize the effects of electrical noise on sensitive circuits.

Working Principle

The ASSR-1219-301E is a solid state relay that works by activating a small control offset to switch on the relay. This is achieved by switching on or off a semiconductor component known as a thyristor. When the control offset is activated, the thyristor charges up quickly, its internal resistance drops suddenly, and it switches on the relay. This causes the output of the ASSR-1219-301E to shift from its normally off state to its normally on state.

When the thyristor is turned off, the internal resistance increases dramatically, and the voltage across the thyristor quickly drops to its normally off state. This allows the relay to be turned off and the output of the relay will shift back to its normally off state.

The ASSR-1219-301E is designed for high performance and precise operation, making it an ideal choice for applications that require reliable switching on or off. The relay can be used in a variety of settings, such as in lighting and temperature control systems, for monitoring voltage and current signals, and for protection from electrical noise. With its accurate offset and long-lasting construction, the ASSR-1219-301E is a reliable and affordable choice for a variety of different applications.
