It is specifically designed for DIN-rail mounting, making it ideal for industrial applications. This optoisolator has a minimum isolation voltage of 2325Vrms and a maximum operating temperature of +85ºC, as well as a maximum surge voltage of 1500V. Additionally, it has an electrical life of up to 1 million operations.

This optoisolator is also suitable for applications that require a highly reliable communication link, such as industrial communication networks. Due to the optoisolator’s natural noise-immunity and excellent signal isolation capabilities, it is frequently used in distributed systems, PLC controllers, and other distributed control systems. It provides Galvanic, electrical isolation, which allows for simple and inexpensive conversion between electrical busses.

Working Principles

The HCNW2201#500 is a four-channel optoisolator with 24mA output. It consists of four channels of Opto-output and a photocoupler to provide electrical isolation between them. The four channels are optically coupled by an LED LED, which is optically coupled to a phototransistor. When the LED is lit, the phototransistor is activated, and the output is logic level. This optoisolator provides excellent noise immunity and electrical isolation between the input and output ports, allowing it to transfer signals over long distances without any interference from electrical noise.

The LED emits light when a voltage is applied to the anode. The light is received by the phototransistor and amplified. The collector terminal of the phototransistor is then connected to Vcc (5V) to switch on the logic level output. When the LED is off, the output is logic low; when it is on, the output is logic high. This optoisolator does not require complex external circuitry and provides reliable operation over long distances. Additionally, it has an electrical life of up to 1 million operations, making it ideal for use in industrial applications where reliability and durability are necessary.

Conclusion

The HCNW2201#500 is an excellent choice for circuitry which requires electrical isolation and noise-immunity. It provides four channels of 24mA output with logic level output, along with a VDE approved UL rated package. It is suitable for a variety of industrial applications, including distributed control systems, PLC controllers, industrial communication networks, and consumer electronics. The HCNW2201#500 has a rated electrical life of up to 1 million operations, ensuring reliable signal transmission over long distances.
