数字输入和输出模块(/O模块)每个PLC (可编程逻辑控制器)的关键部件。具体来说，它们承担PLC的控制，通信和驱动功能。但数字IO模块面临着越来越多的
挑战。这些挑战源于对灵活使用日益增长的需求，以吸同时对系统可靠性市场份额的激烈争夺。不断变化的客户需求也是一个因素。 解决方案的IP保护和访问限制以及其功耗和系统寿命在争夺客户的过程中起着决定性的作用。安全性也变得越来越重要,尤其是在控制驱动器方面。在当今竞争激烈的市场中,长期经验至关重要，简单性、低维护成本和安全数据访问等功能也至关重要。

The Digital Input (DI) module can be used for programmable logic controllers (PLCS) and motor drivers to receive 24V digital inputs from field sensors and switches. The isolation function manages the ground potential difference. The hysteresis power voltage comparator converts the input signal into a logic high or low level. Simultaneously implementing some form of current limitation to avoid excessive use of 24V input current consumption; Power loss is a key issue in compact high-density multi-channel design. The IEC 61131-2 standard for programmable controllers specifies three different types of digital input receivers: Class 1, Class 2, and Class 3. The ideal implementation solution for Class 3 is to consume as close to 2mA current as possible in an open circuit state, with a voltage transition threshold between 5V and 11V.

The digital input and output module (/O module) is a key component of each PLC (programmable logic controller). Specifically, they undertake the control, communication, and driving functions of the PLC. But digital IO modules are facing increasing challenges
Challenge. These challenges stem from the growing demand for flexible usage, while also competing fiercely for market share in system reliability. The constantly changing customer needs are also a factor. The IP protection and access restrictions of the solution, as well as its power consumption and system lifespan, play a decisive role in the process of competing for customers. Security has also become increasingly important, especially in controlling drives. In today’s fiercely competitive market, long-term experience is crucial, as are features such as simplicity, low maintenance costs, and secure data access.
