PD1201S

The PD1201S solid state relay (SSR) is a device for controlling DC or AC power in a variety of applications. It\'s a fast-switching solid-state relay that switches on and off quickly, and is ideal for use in industry, automotive, and medical applications. The device features a high on/off ratio, low power consumption, and excellent reliability. Additionally, the device can be used to control signals as well as control power.The PD1201S is available in two versions, a 4-pin and an 8-pin. The 4-pin version has an on/off ratio of 1:1 and the 8-pin version has an on/off ratio of 5:1. The PD1201S is connected to a control voltage, such as from a microcontroller, to switch the DC or AC load from off to on or vice versa.The on/off ratio of the SSR determines the amount of current that will be supplied to the load. The on/off ratio is ratio is the ratio of the steady state current delivered by the SSR when the control signal is ON, compared to the steady state current delivered when the control signal is OFF. The high on/off ratio is important in applications where the load current must remain within a certain range. For example, in a DC motor, the motor must remain within its rated current at all times, requiring a high on/off ratio from the SSR to keep the current flow within tolerance.The PD1201S features a high current rating of up to 20 amps and a wide operating temperature range of -40 to +85 degrees Celsius. Additionally, the device is resistant to short circuit and electromagnetic interference (EMI). The device has a low on-state voltage drop of 0.2V-4.5V, ensuring that the load receives the required voltage.The PD1201S SSRs feature a low power consumption of only 0.7W for the 4-pin version and 1.8W for the 8-pin version. This low power consumption makes the SSRs ideal for use in low power applications, such as those found in automotive and medical applications.The working principle of the PD1201S SSR is simple. When a control signal is applied to the SSR, the contents of the control signal are stored within the SSR. When the control voltage is removed, the input signal is retained and the SSR will remain in its state of operation. As a result, the PD1201S is ideal for applications where an on/off cycle is necessary, allowing for a fast and reliable switch between states.The PD1201S SSR is a versatile device that can be used in a variety of applications. It is ideal for controlling DC or AC power, and can be used for signal or power switching. Additionally, the device features a high on/off ratio, low power consumption, and excellent reliability, making it perfect for use in industries, automobiles, and medical applications.
