Solid state relays are electrical switches (called power relays) that use semiconductor circuitry to control large voltages and currents.One of the most advanced among them is the CPC1705Y series which is a miniaturized power relay that combines a control circuit and power circuit of an optoelectric isolation into a single chip, optimizing the size and cost.

The CPC1705Y features a wide range of application fields including industrial automation, motor control, relay replacement and any other system that requires isolated control. Due to its minimal size, the device is ideal for use in space-limited equipment.

The operating voltage of the output of the CPC1705Y is up to 240Vac/30VDC and could withstand high pulse loads similarly to a mechanical relay without sacrificing the life expectancy. Its isolation voltage is 5000Vrms/1minute making the device suitable for a variety of industrial applications. It is equipped with several protection components such as surge absorbers, transient suppressors and leakage suppressors which help to prevent the device from abnormal over-current and voltage.

The working principle of the CPC1705Y is straightforward. It contains an internal photo coupler with two isolation barriers which consists of an infrared LED for the input and an opto-transistor for the output. When a voltage is applied to the control input, the internal LED will light up, switching the output controlled on. On the other hand, when the control input voltage is eliminated, the LED stops emitting light and thus the output will turn off again.

Furthermore, the CPC1705Y is equipped with several features for improved safety and reliability. It includes both over current and over-voltage protection which will prevent the output from being turned on while the voltages are too high, protecting the LED from excessive current which could damage or destroy it.

The CPC1705Y series is a highly reliable and cost-efficient solution for many industries such as medical, scientific, and consumer markets. Its small size and high insulation voltage helps to reduce the power consumption as well as the costs for development and manufacturing. Therefore, it is the perfect choice for motor control, relay replacement and any other system that requires isolated control.
