The HE693RTD600 input/output module, also known as the control module, is mainly used to handle data transmission between computers and external devices. It can receive signals from external devices, convert them into a format that can be recognized by the computer, and output computer processing results to external devices. In the fire alarm linkage system, the input and output module is an important part, which can output signal or provide switching signal to control the controlled device, and receive the feedback signal of the device to report to the host.

Second, the working principle

The working principle of the input/output module mainly includes two steps:

Input stage: The HE693RTD600 receives the signal from the external device, converts it into a digital signal that the computer can understand through a specific circuit, and transmits it to the computer host.

Output stage: the HE693RTD600 computer host sends the data that needs to be output to the external device to the input and output module, and the module converts the digital signal into the format that the external device can understand through the corresponding circuit, and transmits it to the external device for display or operation.

Iii. Product description and function

Input/output modules on the market usually 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. For example, the GST-LD-8301 input/output module is a bus control interface that can be used to complete the control of dual-action equipment such as two-step fire reduction rolling shutter doors, water pumps, and smoke exhaust fans. The module has two pairs of normally open and normally closed contacts and two sets of active output, and the input and output have the function of line detection.
