PU516A 3BSE032402R1 controller
ABB PU516A 3BSE032402R1 controller for laser semiconductor industry
Basically, PU516A may be reflected back when light is allowed to pass through the fiber optic cable. Therefore, in order to avoid reverse reflection of the transmitted signal, an optical isolator was used.
It is also known as an optical insulator, optocoupler, and so on. These are mainly used for laser applications. Therefore, the coherence of light will not be affected.
Components of PU516A Optical Isolator
PU516A is mainly composed of three components, namely input and output polarizers. It can be two input and output birefringent plates, acting as a polarizer and Faraday rotator.
The entire operation of the isolator relies on these three components. Now, let’s further understand the main types of optical isolators.

The company has a leading advantage in discontinuing control system components. We have a large inventory and surplus of control system components, as well as some hardware for the discontinued control system. We have also released many new hardware and products to support your existing control system or apply new control technologies. The discontinued “DCS system spare parts, PLC module spare parts,” complete machine and accessories series have a strong advantage. As long as you need PLC products, we can help you find them. The company has a great price advantage.
