CC-PDOB01 输入输出模块 采样周期时间以及外部连接

CC-PDOB01输入输出模块，也称为控制模块，是火灾报警联动系统中的重要组成部分。在有控制要求时，该模块可以输出信号或提供一个开关量信号，使被控设备动作。同时，它还可以接收设备的反馈信号，并向主机报告。市场上的输入输出模块通常可以提供一对无源常开/常闭触点，用以控制被控设备。部分厂家的模块还可以通过参数设定，设置成有源输出。此外，还有双输入输出模块、多输入输出模块等类型。CC-PDOB01 输入输出模块连接在控制器的回路总线上，可以安装在所控设备的附近，也可安装在楼层端子模块箱内。它采用电子写码，可以现场编码，其输出控制逻辑可以根据工程情况进行编程。在选择输入输出模块时，需要考虑模块密度，即同时连接点的数量。一般来说，同时连接点的数量不应超过模块总数的70%。此外，还需要考虑备用输入点的设计，设计输入点总数时应有一定的余量。对于数字输出模块，需要选择输出模式和输出功率，并注意手册中给出的输出功率应大于实际负载所需的功率。对于模拟输入模块，需要考虑模拟值的输入范围、采样周期时间以及外部连接方式等因素。

CC-PDOB01

The CC-PDOB01 input and output module, also known as the control module, is an important component of the fire alarm linkage system. When there are control requirements, the module can output signals or provide a switch signal to activate the controlled equipment. At the same time, it can also receive feedback signals from devices and report to the host. The input and output modules on the market usually provide a pair of passive normally open/normally closed contacts to control the controlled equipment. Some manufacturers can also set their modules to active output through parameter settings. In addition, there are also types such as dual input/output modules and multiple input/output modules. The CC-PDOB01 input and output module is connected to the loop bus of the controller and can be installed near the controlled equipment or inside the floor terminal module box. It adopts electronic coding, which can be coded on site, and its output control logic can be programmed according to the engineering situation. When selecting input/output modules, it is necessary to consider module density, that is, the number of simultaneous connection points. Generally speaking, the number of simultaneous connection points should not exceed 70% of the total number of modules. In addition, it is necessary to consider the design of backup input points, and there should be a certain margin when designing the total number of input points. For digital output modules, it is necessary to select the output mode and output power, and note that the output power given in the manual should be greater than the power required by the actual load. For analog input modules, factors such as the input range of analog values, sampling cycle time, and external connection methods need to be considered.
