ABE7CPA02 模拟量通道是指能够传输连续信号的通道，这些信号通常是未经转换的连续变化量。在模拟量通道中，信号通常是连续的，例如温度、压力、流量和液位等。

ABE7CPA02 模拟量通道的作用是将被控对象的过程参数转换为计算机可以接收的数字量信号。这个过程通常包括信号调理、多路模拟开关切换、前置放大、采样保持和模/数转换等步骤。转换后的数字量信号通过接口电路进入主机系统，完成对过程参数的巡回检测任务。

除了模拟量输入通道，还有模拟量输出通道。ABE7CPA02模拟量输出通道是微型计算机控制系统与执行机构（或控制设备）连接的桥梁。对于能直接接受数字量的执行机构，可由微型机直接输出数字量，而对于只能接受模拟量的执行机构（如电动、气动执行机构、液压伺服机构等），则需要用D/A转换器把数字量变成模拟量后，再带动执行机构。

Model: ABE7CPA02

Product Type: Base connection for counter + analog channels

Number of channels :8

ABE7CPA02 analog channel refers to a channel capable of transmitting continuous signals, which are usually continuous quantities of change without conversion. In analog channels, the signals are usually continuous, such as temperature, pressure, flow, and level.

ABE7CPA02 analog channel is used to convert the process parameters of the controlled object into digital signals that can be received by the computer. This process usually includes steps such as signal conditioning, multichannel analog switching, pre-amplification, sampling hold, and analog/digital conversion. The converted digital signal enters the host system through the interface circuit to complete the itinerant detection of process parameters.

In addition to analog input channels, there are analog output channels. ABE7CPA02 analog output channel is the bridge between microcomputer control system and actuator (or control device). For the actuator that can directly accept the digital quantity, the digital quantity can be directly output by the microcomputer, and for the actuator that can only accept the analog quantity (such as electric, pneumatic actuator, hydraulic servo mechanism, etc.), you need to use the D/A converter to change the digital quantity into the analog quantity, and then drive the actuator.
