F3DIO20802 数字输入输出模块 将数字信号或开关信号进行转换

F3DIO20802数字输入输出模块的作用是将数字信号或开关信号进行转换，以便于PLC（可编程逻辑控制器）能够识别、处理和分析。数字输入模块用于接收外部的机械触点和电子数字式传感器的信号，如二线式光电开关和接近开关等，并将这些外部数字信号转换为PLC内部信号电平。F3DIO20802数字输出模块则将PLC的内部信号电平转换为控制过程所需的外部信号电平，用于驱动各种调节机构或控制设备，如启动停止、接通和断开等。

F3DIO20802数字输入输出模块有多种类型，包括数字量输入模块、数字量输出模块、模拟量输入模块等。数字量输入模块用于连接外部的机械触点和电子数字式传感器，将现场传来的外部数字信号转换为PLC内部信号电平。数字量输出模块则将PLC的内部信号电平转换为控制过程所需的外部信号电平，同时有隔离和功率放大的作用。模拟量输入模块用于接收模拟量信号，如电压和电流等，并将其转换为PLC内部能够处理的数字信号。

此外，还有一些数据采集器，如DAM-5088模块，它是工业级数字/开关量输入输出采集器，适用于工业现场的多种控制系统。它可以采集8路开关量输入和8路开关量输出信号，并配置有隔离的RS485接口，可单独与PC或PLC通信，也可以与多个485模块组网使用。

The function of the F3DIO20802 digital input/output module is to convert the digital signal or switching signal, so that the PLC (programmable logic controller) can recognize, process and analyze. The digital input module is used to receive signals from external mechanical contacts and electronic digital sensors, such as two-wire photoelectric switches and proximity switches, and convert these external digital signals into PLC internal signal levels. The F3DIO20802 digital output module converts the internal signal level of the PLC to the external signal level required for the control process, which is used to drive various regulating mechanisms or control devices, such as starting, stopping, connecting and disconnecting.

F3DIO20802 digital input and output module has many types, including digital input module, digital output module, analog input module and so on. The digital input module is used to connect the external mechanical contact and the electronic digital sensor, and convert the external digital signal from the field into the PLC internal signal level. The digital output module converts the internal signal level of the PLC to the external signal level required for the control process, and has the role of isolation and power amplification. The analog input module is used to receive analog signals, such as voltage and current, and convert them into digital signals that can be processed within the PLC.

In addition, there are some data collectors, such as the DAM-5088 module, which is an industrial grade digital/switching input/output collector suitable for a variety of control systems in industrial sites. It can collect 8 switch input and 8 switch output signals, and is configured with isolated RS485 interface, can communicate with PC or PLC alone, can also be used with multiple 485 modules networking.
