TRICONEX 3515 | TRICON3515 | Invensys Pulse Totalizer | Pulse Input PI Module.The Triconex 3515 is a Pulse Input (PI) module that provides optical isolation. Optical isolation is a method of ensuring that electrical circuits are electrically isolated from each other. This isolation is achieved by using light, rather than electrical signals, to transmit information.

Optical isolation is particularly useful in industrial applications where safety and reliability are paramount. For example, it can be used in high-voltage environments where electrical insulation is necessary, or in situations where electrical noise could interfere with the operation of sensitive electronic devices.

The Triconex 3515 module is part of the Triconex series, which is known for its high-frequency pulse input capabilities. This means it can handle rapid changes in voltage or current, making it suitable for applications that involve fast-moving machinery or rapidly changing conditions.（Click for related modules:3721、3009、4351B、More）
