数字输出就是数字信号的输出，用于传输声音的信号分为：数字信号、模拟信号和光学信号。

ABB-PM876数字输出是一种电子学技术，它通过将模拟信号转换为数字信号，以便在计算机、数字音频设备和其他数字系统中进行处理、存储和传输。数字输出通常采用二进制编码，即使用0和1表示数字信号的不同电平，从而实现对模拟信号的数字化处理。

模拟输出和数字输出的主要区别如下：

信号源工作原理不同：ABB-PM876模拟信号采用连续信号，一般采用连续变化的电磁波或采用连续变化的信号电压表示；数字信号处理的是离散信号，数字信号通常使用1和0表示。

输出方式不同：ABB-PM876模拟信号一般通过传统的传输线路（例如电话网、有线电视网）来传输；数字信号采用断续变化的电压或光脉冲来表示时，一般则需要用双绞线，和光纤介质等将通信双方连接起来，才能将信号从一个节点传到另一个节点。

PM876 3BDH000607R1 ABB Digital Output Number 6 is programmable

The digital output No. 1 of the process I/O board DATX 110 is programmable. When parameter 13.01=0, the rotor

The resistance control can manage the contactor KO's DO1 number.

In order to extend the service life of the crane friction coupled cable drum, its motor can be disconnected unless

When the brake is raised and the speed reference is raised, it should roll during lifting. Usage parameter

If set to 1,DO no.1 will have this function.

When the above functions are not required, DO 1 can be used for extension

Thyristor module. As soon as the action begins, the wind and fan will be activated and will be in

The movement has stopped. When the parameter is set to 2, DO 1 has this function. Actual temperature

The radiator is shown as signal 05.94.

Set to 3 for lifting systems with an oversized motor that should lift and lower the full load for a limited time in the event of a single motor failure. The value 3 is used in the macro that describes the rescue mode. this

The thyristor cooling fan will always operate in rescue mode. In such a short time, the life of the fan is usually only

A third, but the start-up temperature of the thyristor will be lower.

The digital output is the output of the digital signal, the signal used to transmit the sound is divided into: digital signal, analog signal and optical signal.

ABB-PM876 Digital Output is an electronics technology that converts analog signals into digital signals for processing, storage, and transmission in computers, digital audio devices, and other digital systems. The digital output is usually binary coded, that is, 0 and 1 are used to represent different levels of the digital signal, so as to realize the digital processing of the analog signal.

The main differences between analog and digital outputs are as follows:

The working principle of the signal source is different: ABB-PM876 analog signal adopts continuous signal, which is generally expressed by continuously changing electromagnetic wave or continuously changing signal voltage; Digital signals deal with discrete signals, and digital signals are usually represented by 1s and 0s.

The output mode is different: ABB-PM876 analog signals are generally transmitted through traditional transmission lines (such as telephone networks, cable television networks); When the digital signal is represented by intermittent changes in voltage or light pulses, it is generally necessary to connect the two communication parties with twisted pairs, and optical fiber media, in order to transmit the signal from one node to another.
