Optoisolators are used to protect sensitive circuits from the effects of high voltage spikes or large transients. In addition to protecting the connected circuits from electrical noise, optoisolators provide electrical isolation between the two circuits making them an ideal choice for many applications where safety is paramount. One such device is the PS2933-1-AX optoisolator, a transistor, photovoltaic output type of optoisolator, which offers a unique combination of features and performance.

The PS2933-1-AX is a 4-pin device that provides isolated power between actuators, such as contactors, relays or motor controllers, and a 5V logic circuit such as a PLC, motion controller or PC. It has an on-off control from the logic side (input) for switching on and off the power via the output side (output). Its isolation voltage is 500Vrms, which isolates sensitive circuits from unexpected noise or voltage spikes, providing an additional layer of protection.

In order to understand the working principle of the PS2933-1-AX optoisolator, one must look at the two main components which make up the device—the photovoltaic cell (PV cell) and the phototransistor (PT). The PV cell is the optical element of the optoisolator, which converts light into electrical energy. When light is incident onto the cell, it creates an electrical potential across the cell’s terminals, which is proportional to the intensity of the light. The PT is the electrical element of the optoisolator, which is used to detect, amplify, and process the electrical signal produced by the PV cell. When the light incident on the PV cell is sufficient to create an electrical potential across its terminals, the signal is transmitted to the PT, producing a current flow between the collector and emitter.

The working principle of the PS2933-1-AX optoisolator occurs when a surge, spike, or transient provided by the input side (logic) is detected by the PV cell. The light incident on the PV cell is then converted to an electrical signal which is transmitted to the PT where it is amplified to a higher voltage. This amplified signal is then transmitted toward the actuator, such as a contactor, relay or motor controller, switching the current flow on or off. By producing a differential voltage between the input and output sides of the optoisolator, the electrical noise or other transients are blocked, preventing them from damaging the connected circuits.

The PS2933-1-AX optoisolator is used extensively in many industries, including automotive, aerospace, industrial automation, and process control. It is used in motor control systems and HVAC systems, as well as in motion control systems and environmental monitoring systems. It is also used in safety systems to monitor alarm and detect fault conditions.

Due to its ease of installation, reliability, and cost effective construction, the PS2933-1-AX optoisolator is quickly becoming the industry standard for applications requiring electrical isolation and protection from transients. With its unique combination of features, performance, and reliability, the PS2933-1-AX optoisolator is an ideal choice for protecting sensitive circuits from noise and transients.
