This is a digital isolation and termination circuit. This circuit uses The CLT3-4 that is a digital termination device with quadruple input. The CLT3-4 is designed for 24 V DC automation applications. The CLT3-4 drives an isolating opto-coupler and gives the front-end circuitry of a digital input module (I/O) in industrial automation. Here is the circuit:
digital Isolation and Termination circuit schematic
This circuit has a four channels configuration. It provides a high-density termination by minimizing the external components count. To reduce the printed board size this circuit is housed in a TSSOP20 surface mount package.

This circuit has a serial current limiting circuit, an opto-coupler driver and an input voltage protection. The connection between the logic input and the associated switch or high side sensor is terminated.

This article describes the Digital Isolation and Termination (TSSOP20). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:TSSOP20.
