FBM222 P0926TL 输入输出模块 同时可以接收设备的反馈信号

FBM222 P0926TL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，是火灾报警联动系统中重要的组成部分。此外，它也是计算机与外部设备进行通信的桥梁和纽带。它通过接收并处理从键鼠扫描仪等输入设备送来的数据或命令，向CPU发送控制命令和数据。

输入输出模块在什么情况下会输出信号？

FBM222 P0926TL输入输出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。当控制器接收到探测器的报警信号后，根据预先编入的程序，控制器通过总线将联动控制信号输送到输出模块，输出模块启动需要联动的消防设备；设备动作后会接受一个信号回答。FBM222 P0926TL此模块所需输入信号为常开开关信号，一旦开关信号动作，模块将此开关信号通过联动总线送入控制器，联动控制器产生报警并显示出动作设备的地址号。

FBM222 P0926TL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。

FBM222 P0926TL 输入输出模块 同时可以接收设备的反馈信号

FBM222 P0926TL Input and output module is also known as the control module, when there is a control requirement, it can output signals, or provide a switching signal, so that the controlled device can act, and at the same time, it can receive the feedback signal of the device to report to the host. It is an important part of the fire alarm linkage system. In addition, it is also the bridge and link between the computer and external devices. It sends control commands and data to the CPU by receiving and processing data or commands from input devices such as keyboard and mouse scanners.

When does the I/O module output a signal?

The FBM222 P0926TL input/output module can output signals when there is a control requirement, or provide a switching signal to make the controlled device act. When the controller receives the alarm signal of the detector, according to the pre-programmed program, the controller transmits the linkage control signal to the output module through the bus, and the output module starts the fire fighting equipment that needs linkage; The device responds with a signal when it acts. FBM222 P0926TL The required input signal of the module is the normally open switch signal. Once the switch signal is activated, the module sends the switch signal to the controller through the linkage bus, and the linkage controller generates an alarm and displays the address number of the operating device.

The role of the FBM222 P0926TL input/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.
