Optoisolators - Transistor, Photovoltaic Output, are among the most popular optoelectronic devices employed across numerous application fields. They are specifically designed indicate a digital signal\'s presence or absence as output under various scenarios, regardless of the input conditions. One such Optoisolator, the PS2841-4B-AX, can be used to deliver a consistent 3.5mA switching current and offers superior efficiency even under varying voltage and temperature ranges.

The PS2841-4B-AX is a fast-switching AC Input Optoisolator that enables efficient signal detection and activation of loads both on AC and DC lines. It is highly compatible with low voltage input circuits, making it an ideal optoelectronic component in the fields of industrial automation and sensor applications. Therefore, it is widely used in power systems, motor control circuits, medical equipment, and consumer electronics.

The key working principle behind the PS2841-4B-AX is that it detects, isolates, and transmits signals through an optoelectronic system. It consists of an AC input that contains a light source and an LED optically connected to a transistor output. When an AC signal is introduced to the input, an optical pulse is emitted by the source and received by the LED. This triggers the transistor at the output to switch, thus providing the isolated output needed to activate a load.

The PS2841-4B-AX features an AC input voltage range of 3 to 350VAC, with a switching current ranging from 0.25mA to 3.5mA and a switching voltage range from 2V to 28V. This allows for a large reduction and absorption of noise, providing enhanced signal stability while protecting load components from damage. Additionally, it provides protection against false-triggering and interference from noise and static electricity, presenting users with worry-free and reliable system performance.

Furthermore, the PS2841-4B-AX contains a hysteresis circuit inside that automatically sets the current level for “ON” to be approximately 3 times higher than the “OFF” current level. This ensures that even when the input signal is disturbed, the components are shielded from overload and interference that may cause errors. Additionally, the high current transfer ratio of 1000:1 and the superior common mode rejection ratios up to 50 dB makes the PS2841-4B-AX one of the most stable and efficient signal-switching optoelectronic options available.

Due to its reliable and precise electronic pulse isolation technology, the PS2841-4B-AX is ideal for a wide range of AC input optoisolator applications within industrial, power, medical, and consumer electronics fields. It features a long life span, simplified circuit design, and superior AC input signal isolation. Ease of installation coupled with proven reliability makes the Optoisolator - Transistor, Photovoltaic Output, one of the Industry’s most sought-after components.
