T9402  是一款数字输入模块 三重冗余结构

T9402 数字输入模块具有以下特点：

• 三重架构：具备三个独立通道，每个通道能独

• 立采样和处理。这种三重冗余结构极大地提高了系统的可靠性和容错能力，即使一个或两个通道出现故障，系统仍能正常工作。

• 投票逻辑：采用投票逻辑算法来确定每个通道的输出值。该算法可以在部分通道故障的情况下，确保输出值的正确性，增强了系统输出的稳定性和准确性。
• 广泛的诊断覆盖范围：能够对电源、通道输入和内部电路等进行监控，帮助识别和隔离故障。这有助于及时发现问题并采取相应的维护措施，降低系统故障风险，提高系统的可维护性。
• 多通道输入：拥有 16 个数字输入通道，且每个通道可以配置为正常打开（NO）或正常关闭（NC）状态，还具有测试模式，可用于验证输入通道的操作，为各种复杂的输入信号监测和控制需求提供了灵活的解决方案。

T9402 数字输入模块通常应用于对可靠性和安全性要求极高的工业控制领域，如发电、石化、石油和天然气、钢铁厂、水泥厂等行业，这些行业的生产过程需要高度稳定和可靠的控制系统来保障运行安全和生产效率。

The T9402 digital input module has the following characteristics:

Triple architecture: It has three independent channels, each of which can independently sample and process. This triple redundancy structure greatly improves the reliability and fault tolerance of the system, even if one or two channels fail, the system can still work normally.

Voting logic: Use voting logic algorithm to determine the output value of each channel. This algorithm can ensure the correctness of output values in the event of partial channel failures, enhancing the stability and accuracy of system output.

Wide diagnostic coverage: capable of monit

oring power supplies, channel inputs, and internal circuits to help identify and isolate faults. This helps to detect problems in a timely manner and take corresponding maintenance measures, reducing the risk of system failures and improving the maintainability of the system.

Multi channel input: It has 16 digital input

channels, and each channel can be configured to be in normal open (NO) or normal closed (NC) state. It also has a test mode that can be used to verify the operation of the input channels, providing flexible solutions for various complex input signal monitoring and control requirements.

The T9402 digital input module is commonly used in industrial control fields that require extremely high reliability and safety, such as power generation, petrochemicals, oil and gas, steel plants, cement plants, and other industries. The production processes of these industries require highly stable and reliable control systems to ensure operational safety and production efficiency.
