SDK-C0167-1-12004-08-01-SBS07M076B  输入输出模块 可以接收设备的反馈信号

SDK-C0167-1-12004-08-01-SBS07M076B 输入输出模块，也称为控制模块，在有控制要求时可以输出信号，或者提供一个开关量信号，使被控设备动作，同时可以接收设备的反馈信号，以向主机报告。在火灾报警联动系统中，输入输出模块是一个重要的组成部分。

SDK-C0167-1-12004-08-01-SBS07M076B输入输出模块的作用包括接收设备的反馈信号，以及根据工程情况编程输出控制逻辑。它可以提供一对无源常开/常闭触点，用以控制被控设备。部分厂家的模块可以通过参数设定，设置成有源输出。市场上的输入输出模块都可以提供一对无源常开/常闭触点，用以控制被控设备，部分厂家的模块可以通过参数设定，设置成有源输出（如海湾GST-LD-8301），相对应的还有双输入输出模块、多输入输出模块等等。

此外，还有一些关于输入输出模块的种类和选择注意事项：

数字量/模拟量信号：SDK-C0167-1-12004-08-01-SBS07M076B数字量输入输出信号是开关量信号，1或者0，而模拟量信号有电压或者电流信号，一般是变送器传过来的信号。

输入模块的选择：需要考虑电压等级、保护形式、模块密度和备用输入点的设计。

输出模块的选择：需要注意输出模式和输出功率的选择，选择时应使手册中给出的输出功率大于实际负载所需的功率。

模拟输入模块的选择：需要注意模拟值的输入范围。模拟输入模块有各种输入范围，包括0 ~ 10V、10V、4 ~ 20 mA等。

总之，根据实际需要选择合适的输入输出模块类型和规格是至关重要的。

SDK-C0167-1-12004-08-01-SBS07M076B  输入输出模块 可以接收设备的反馈信号

SDK-C0167-1-12004-08-01-SBS07M076B Input and output module, also known as the control module, can output signals when there is a control requirement, or provide a switching signal to make the controlled device act, and can receive the feedback signal of the device to report to the host. In the fire alarm linkage system, the input and output module is an important component.

SDK-C0167-1-12004-08-01-SBS07M076B The function of the input and output module includes receiving the feedback signal of the device, and programming the output control logic according to the engineering situation. It can provide a pair of passive normally open/normally closed contacts to control the controlled device. Some manufacturers' modules can be set to active output through parameter setting. Input and output modules on the market can provide a pair of passive normally open/normally closed contacts to control the controlled equipment, some manufacturers of the module can be set through parameters, set to active output (such as Gulf GST-LD-8301), the corresponding dual input and output modules, multiple input and output modules and so on.

In addition, there are some considerations regarding the types and selection of input and output modules:

Digital/analog signal: SDK-C0167-1-12004-08-01-SBS07M076B Digital input and output signals are switching signals, 1 or 0, while analog signals have voltage or current signals, which are generally signals transmitted by transmitters.

Input module selection: Voltage level, protection form, module density and alternate input point design need to be considered.

Selection of output module: Pay attention to the selection of output mode and output power, and make the output power given in the manual greater than the power required by the actual load.

Selection of analog input modules: Attention should be paid to the input range of analog values. Analog input modules are available in various input ranges, including 0 ~ 10V, 10V, 4 ~ 20 mA, etc.

In short, it is crucial to choose the right type and specification of input and output modules according to the actual needs.
