1.1功能概述 
1.1 Function Overview 

GC-3822模块是集成2路温度传感器（PT100）输入通道的I/O模块。该模块可用于实时采集温度信息，并将采集到的数值通过内部总线发送给GCAN-PLC-3/4/5系列主控模块或GCAN-8X00系列耦合器。该模块可与其他任何GC系列IO模块搭配使用，实现工业自动化或分布式控制系统中温度模拟量数据的采集与处理。 
The GC-3822 module is an I/O module that integrates two temperature sensor (PT100) input channels. This module can be used to collect real-time temperature information and send the collected values to the GCAN-PLC-3/4/5 series main control module or GCAN-8X00 series coupler through an internal bus. This module can be used in conjunction with any other GC series IO module to collect and process temperature analog data in industrial automation or distributed control systems.
