Introduction

Solid State Relays (SSR) are a type of solid-state electronic device that offers an alternative to conventional electromechanical relays. SSRs have no mechanical switching contacts, but control electrical load currents via solid-state electronic switch devices such as MOSFETs, triacs, or thyristors. Using SSRs offer several advantages over electromechanical relays, such as fast switching, high-speed protection, high reliability, long life, isolation, and, in many cases, a lower cost.

AQC1A1-ZT24VDC application field and working principle

The AQC1A1-ZT24VDC SSR is a zero-crossing, 24-volt DC, 2-channel opto-coupler output SSR. It is used to control DC loads in a wide range of applications. Its main features include AC or DC control, adjustable turn-on delay, voltage surge suppression, and LED status indicator. It also has wide load current range and is suitable for high-reliability applications.

The AQC1A1-ZT24VDC SSR works by pairing an opto-coupler with a thyristor in a repeated cycle. When the opto-coupler detects an input signal, it sends a signal to the thyristor, causing it to turn on. This results in current flowing through the load, thus switching it on. When the input signal reaches zero, the thyristor turns off and the current is cut off from the load, thus switching it off.

The AQC1A1-ZT24VDC SSR includes a number of features that make it suitable for a wide range of applications. It has a wide load current range of 0.05A to 10A, so it is suitable for small to medium loads. It has surge suppression circuitry, so it is suitable for use with motors and other load current devices with large starting currents. It has an adjustable turn-on delay to reduce the inrush current when switching on. It is also isolated from the load, which is important for applications that require electrical isolation between the load and the controlling device. Finally, it has a built-in LED status indicator that provides feedback on whether the relay is closed or open.

Conclusion

The AQC1A1-ZT24VDC is a reliable, versatile, and cost-effective SSR that is suitable for a wide range of applications. It has a wide current range, adjustable turn-on delay, and offers high electrical isolation. It is also easy to install and has an LED feedback indicator for easy monitoring. In conclusion, the AQC1A1-ZT24VDC is a reliable and cost-effective choice for controlling DC loads in a variety of applications.
