Solid State Relays

The 4D1240 is a 4-channel, high-power, compact SSR – solid state relay – that can be employed in a wide range of industrial applications. It features high-speed switching, small size, fast response time, and high efficiency.

Solid state relays switch electrical loads using the power of semiconductors, making the switching process faster, quieter, and more reliable than with traditional mechanical relays. Comparing with other SSRs, the 4D1240 stands out due to its high power capabilities, allowing it to drive up to 10A of load current in each of its four channels.

The 4D1240 is also incredibly versatile, and can be used in a variety of applications. The device’s ability to drive both AC and DC loads, as well as its ability to control loads within a range of 0.1 – 480V, make it suitable for a range of applications, from controlling heaters and lights, to controlling motors, compressors, and even pumps.

The 4D1240 is easy to set up, as it does not require complex installation or configuration. It connects directly to the AC power supply, load, and control input, and it operates according to the instructions provided by its digital input. The 4D1240 features an LED indicator that shows when the relay is switched on or off.

The 4D1240 is based on a mosfet power switch, and works according to the principle of zero-voltage crossover. This means that the output switches as soon as the input voltage crosses the zero-voltage threshold. This eliminates the need for external protection circuitry, and results in faster switching times.

The 4D1240 is rated to operate from 0°C up to +70°C, and can dissipate up to 40W of heat at room temperature. It uses a soft-start feature, which minimizes inrush current, protecting any connected loads and extending relay life. The 4D1240 also features a reversible snubber circuit, further protecting connected loads.

In conclusion, the 4D1240 is a powerful and versatile solid state relay that provides fast, reliable switching for a wide range of industrial applications. It is easy to install and set up, and offers unmatched power capabilities, making it the perfect choice for any application that needs reliable, fast switching.
