GE D20 EME的框架 (1) 可以将输入的数字量信号转换为输出的控制信号

数字量控制模块是一种用于控制数字量的模块。它可以将输入的数字量信号转换为输出的控制信号，并对输出信号进行控制。数字量控制模块通常用于控制机械设备和自动化系统，例如电机、开关、传感器等。 数字量控制模块通常包括输入模块和输出模块。输入模块用于连接外部的数字量信号，并将其转换为内部信号。输出模块用于输出控制信号，控制外部设备的运行。输出模块大致分为三种： – 继电器输出：模块可以带交直流负载，有触点，容易坏。 – 三极管输出：带直流负载，负载电流较小，一旦过流极易损坏。 – 可控硅输出：无触点，寿命长。

Digital quantity control module is a module used to control digital quantity. It can convert the input digital signal into the output control signal, and control the output signal. Digital quantity control modules are commonly used to control mechanical equipment and automation systems, such as motors, switches, sensors, etc.

Digital quantity control module usually includes input module and output module. The input module is used to connect external digital signals and convert them into internal signals. The output module is used to output control signals and control the operation of external devices. Output modules are broadly divided into three types:
– Relay output: The module can be loaded with AC and DC, with contacts, easy to break.
– Transistor output: with DC load, the load current is small, once the current is too easy to damage.
– Thyristor output: no contact, long life.
