140DAI74000是施耐德的一款輸入輸出模塊，也被稱為控制模塊。
在有控制要求時，它可以輸出信號，或者提供一個開關量信號，使被控設備動作，同時可以接收設備的反饋信號，以向主機報告。這種模塊在火災報警聯(lián)動系統(tǒng)中是一個重要的組成部分。市場上的輸入輸出模塊都可以提供一對無源常開/常閉觸點，用以控制被控設備，部分廠家的模塊可以通過參數(shù)設定，設置成有源輸出。
140DAI74000的應用場景包括但不限于以下幾種：
工業(yè)自動化系統(tǒng)：可以作為工業(yè)自動化系統(tǒng)中的輸入輸出模塊，用于接收和輸出各種信號，實現(xiàn)設備的自動化控制。
智能家居系統(tǒng)：可以作為智能家居系統(tǒng)中的輸入輸出模塊，用于接收和輸出各種智能設備的信號，實現(xiàn)家居的智能化控制。
樓宇自動化系統(tǒng)：可以作為樓宇自動化系統(tǒng)中的輸入輸出模塊，用于接收和輸出各種樓宇設備的信號，實現(xiàn)樓宇的自動化控制。

140DAI74000

The 140DAI74000 is an input/output module from Schneider, also known as a control module.
When there is a control requirement, it can output a signal or provide a switching signal to make the controlled device act, and at the same time, it can receive a feedback signal from the device to report to the host. This module is an important component in 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 device, and some manufacturers’ modules can be set to active output through parameter setting.
The 140DAI74000 can be used in the following scenarios:
Industrial automation system: can be used as an input and output module in industrial automation system, used to receive and output various signals, to achieve automatic control of equipment.
Smart home system: It can be used as an input and output module in the smart home system to receive and output signals from various smart devices to achieve intelligent control of the home.
Building automation system: can be used as the input and output module in the building automation system, used to receive and output signals of various building equipment to achieve automatic control of the building.
