IC697MDL251输入模块是一种与外部发信装置相接的组件，主要用于接收外部信号，并将其转换为CPU或其他计算机模块可接受的信号。在消防系统中，输入模块通常用于接收消防设备输入的常开或常闭开关量信号，并将现场部件动作信息传回火灾报警控制器。例如，它可以监控现场压力开关、水流指示器、信号蝶阀、防火阀等设备的状态。对于不能编码的点型探测器和手动报警按钮，以及线型探测器和管路采样吸气式感烟探测器，通常需要设置输入模块。

IC697MDL251输入模块在接收到信号后，可能还会对信号进行处理，如去除噪声、校验数据的完整性等，以确保传输的准确性和可靠性。处理后的数据会通过计算机内部的总线或接口传输到主机或其他需要使用该数据的模块。此外，输入模块通常支持中断机制，当有新的输入信号时，可以立即中断主机的正常运行，向主机发出中断请求，确保输入信号不会被忽略或漏掉。

The IC697MDL251 input module is a component connected to an external transmitting device, which is mainly used to receive external signals and convert them into signals acceptable to the CPU or other computer modules. In the fire control system, the input module is usually used to receive the normally open or normally closed switch signal input from the fire control equipment, and transmit the action information of the field components back to the fire alarm controller. For example, it can monitor the status of field pressure switches, water flow indicators, signal butterfly valves, fire valves and other equipment. An input module is usually required for point detectors and manual alarm buttons that cannot be coded, as well as linear detectors and line sampling aspirated smoke detectors.

After receiving the signal, the IC697MDL251 input module may also process the signal, such as removing noise and verifying data integrity, to ensure the accuracy and reliability of transmission. The processed data is transmitted through the bus or interface inside the computer to the host or other modules that need to use the data. In addition, the input module usually supports an interrupt mechanism, when there is a new input signal, it can immediately interrupt the normal operation of the host, and send an interrupt request to the host to ensure that the input signal will not be ignored or missed.
