SCYC51040 ABB 输入输出模块也称为控制模块

SCYC51040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，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。

SCYC51040模块输入端如果设置为“常开检线”状态输入，模块输入线末端（远离模块端）必须并联一个4.7kΩ的终端电阻；模块输入端如果设置为“常闭检线”状态输入模块输入线末端（远离模块端）必须串联一个4.7kΩ的终端电阻。模块为有源输出时,有源输出端应并联一个4.7kΩ的终端电阻，并串联一个IN4007二极管。

SCYC51040

SCYC51040 input and output module is also known as the control module, when there are control requirements can output signals, or provide a switching signal, so that the controlled equipment action, at the same time can receive the feedback signal of the equipment, to report to the host, is an important part of the fire alarm linkage system. 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.

When the SCYC51040 fire alarm, the alarm controller starts the external control equipment to be linked through the output module, such as smoke exhaust valve, air supply valve, fire shutter door, fan, alarm bell, etc., and can accept the action of the equipment.
The output module is connected to the loop bus of the controller and can be installed near the control device or in the floor terminal module box. Using electronic coding, can be field coding. The output control logic of the output module can be programmed according to the project situation. 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.

If the input end of the SCYC51040 module is set to the “normally open check line” state input, the end of the module input line (away from the module end) must be connected with a 4.7kΩ terminal resistor; Module input If the status of the input module is normally closed, a 4.7kΩ terminal resistor must be connected in series at the end of the input module input line (away from the module end). When the module has an active output, the active output should be connected by a 4.7kΩ terminal resistor and an IN4007 diode in series.
