Solid State Relays

A1225E-10 solid state relays are designed primarily for AC switching applications. They are miniature devices that offer high performance and low cost characteristics.

A1225E-10 is a three-terminal, zero-cross, monostable, zero-current switch (or SSR). It is generally often used to replace two- or three-pole electromechanical relays. This SSR is specifically designed to switch AC power lines with a capacitive load.

In addition to their small size, A1225E-10 solid state relays offer several advantages over mechanical relays, such as: switching speed, contact life, and fail-safe reliability.

A1225E-10 features a zero-cross switching circuit that eliminates the need for a physical AC contactor in many applications. This SSR is also designed with a specially shaped arc that dissipates arc progression, making it safer than many other SSRs.

A1225E-10 is a three-terminal solid state relay with the following pin-out:

• Pin 1: Anode (A) – Input voltage for the relay
• Pin 2: Cathode (K) – Ground for the relay
• Pin 3: Drain (D) - Output voltage of the relay

The A1225E-10 solid state relay is typically found in industrial applications, such as in industrial electronics, industrial automation, and in power electronics. It is particularly useful for applications where high switching speed or a high reliability is required.

The A1225E-10 solid state relay works by using semiconductor device logic gate. It uses the logic gate to create a power bridge, which connects the input voltage to the output. This power bridge is turned on or off depending on the logic input. When the logic circuit is active, a voltage is applied to the relay, which creates a current flow from the anode to the cathode. The current flow then actuates the power bridge, which turns the output on or off.

The A1225E-10 is generally operated using a standard AC line voltage, as it is rated for up to 710V AC and 6A. The operational temperature range is between -32°F and 176°F (-35°C and 80°C), but it can handle up to 212°F (100°C).

A1225E-10 solid state relays are reliable, long lasting, highly efficient alternatives to traditional electromechanical relays. They offer a low cost option when compared to more expensive optocouplers, and they offer fast response times and high noise immunity. In addition, they require minimal power-up time and they also reduce system power consumption. In general, A1225E-10 solid state relays are well-suited for a variety of applications, including motor control, building automation, HVAC, and lighting control.
