Solid state relays (SSRs) are electrical switches that provide a better alternative to mechanical relays in applications ranging from industrial to consumer electronics. SSRs are used for diverse applications such as industrial automation, motor control circuits, audio/visual (A/V) systems, home automation, robotics, and more. The GNR25DCZ SSR is a type of SSR specifically designed for use in industrial automation applications, offering a number of unique features and advantages. This article will outline the GNR25DCZ\'s application field and working principle.

The GNR25DCZ is a zero-crossing ultra-sensitive DIN-Rail mounted solid state relay rated at 25A with zero voltage/current switching (ZVS) technology and built-in LED indication. The compact size and DIN-Rail mount makes the GNR25DCZ ideal for use in control panels and when space is at a premium. The GNR25DCZ is designed for the control of AC loads in lighting, hoses and ventilation systems, industrial automation with pulse-width modulation outputs, and AC power control. The GNR25DCZ offers a range of features including LED indication for input and output status, over-voltage protection, reverse polarity protection, zero-cross AC output, and low power turn-on and turn-off capability.

The working principle of the GNR25DCZ is based on phase control technology, which is the process of controlling the power supplied to an AC load by switching the load on and off at different points of the AC waveform. When the load is turned on, the voltage rapidly rises to its peak value, and when the load is turned off, the voltage rapidly drops back to zero. This process allows for precise control of the AC load. The GNR25DCZ utilizes ZVS (zero-voltage/current switching) technology to achieve ultra-sensitive and reliable switching control.

When the GNR25DCZ is triggered, a small switching current is sent to the AC load. This switching current is used to detect the zero-crossing point of the AC power line voltage. At this exact point, the output of the GNR25DCZ is switched on or off, resulting in low EMI/RFI emission and precise control of the AC load.

The GNR25DCZ offers a number of advantages. It is UL, cUL and TÜV approved, making it suitable for use in a wide range of industrial settings. The DIN-Rail mounted design makes for easy installation and integration into control panels, while the ZVS technology ensures high precision control with low EMI/RFI emission. In addition, the GNR25DCZ provides over-voltage and reverse polarity protection, LED status indication, and low power turn-on and turn-off capability.
