Screen operation

① Local color screen intelligent processing:The device's built-in 2.4-inch screen can display the input and output status of 24 circuits in real time, and the linkage of input and output can be set through the screen.
② External sensors:Supports the integration of external human counting sensors, temperature and humidity sensors, lighting sensors, and carbon monoxide sensors. Through a color screen automation system, real-time collection and intelligent response of sensor data are achieved.
③ Multi language switching:The system language supports switching between Chinese and English,

④ Baud rate modification:Directly modify the baud rate of two 485 ports through the local color screen, making the operation more convenient.

⑤ Device Address Modification:Modifying device address through local color screen makes the operation more convenient.
* 24 independent high-power 16A relay, supporting 24 digital signal input detection, real-time data display and parameter configuration through local color touch screen, without relying on the cloud, directly setting values, delay actions, linkage strategies through the screen, suitable for intelligent room management, production line equipment control, building automation and other application scenarios.

Setting Guide

1. INPUT/Input Status

① This page displays the status of 24 DIs. When a DI is connected, the corresponding icon's outer circle is displayed in yellow; When DI is disconnected, the outer circle of the corresponding icon is displayed in black.

② Click on the corresponding icon, enter the password, and enter the DI linkage settings page. After sliding and selecting the left circle of the linked relay, this logic will automatically take effect. If the left circle is not selected, this automatic logic will not be executed.

2. OUTPUT/Output Status

① This page displays the status of 24 relays D0. When the relay is turned on, the outer circle of the corresponding icon displays yellow. When the relay is turned off, the outer circle of the corresponding icon displays black.
