描述
GE D20 EME的框架 (1) 可以將輸入的數(shù)字量信號(hào)轉(zhuǎn)換為輸出的控制信號(hào)
數(shù)字量控制模塊是一種用于控制數(shù)字量的模塊。它可以將輸入的數(shù)字量信號(hào)轉(zhuǎn)換為輸出的控制信號(hào),并對(duì)輸出信號(hào)進(jìn)行控制。數(shù)字量控制模塊通常用于控制機(jī)械設(shè)備和自動(dòng)化系統(tǒng),例如電機(jī)、開關(guān)、傳感器等。 數(shù)字量控制模塊通常包括輸入模塊和輸出模塊。輸入模塊用于連接外部的數(shù)字量信號(hào),并將其轉(zhuǎn)換為內(nèi)部信號(hào)。輸出模塊用于輸出控制信號(hào),控制外部設(shè)備的運(yùn)行。輸出模塊大致分為三種: – 繼電器輸出:模塊可以帶交直流負(fù)載,有觸點(diǎn),容易壞。 – 三極管輸出:帶直流負(fù)載,負(fù)載電流較小,一旦過流極易損壞。 – 可控硅輸出:無觸點(diǎn),壽命長。

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.
