product description 


The technical parameters of discrete output module include the following aspects:


Output type: There are many output types of discrete output modules, such as dry contact, 

transistor and SSR (solid state relay) output. Select the appropriate output type according 

to the specific application requirements to meet the control requirements.

Output voltage and current: The output voltage and current of the discrete output module 

are important technical parameters. According to the voltage and current requirements of 

the controlled object, the appropriate output voltage and current range is selected to ensure 

the accuracy and reliability of the control action.

Output waveform: The output waveform of the discrete output module is also an important 

technical parameter. Generally speaking, the output waveform of the discrete output module 

should be a square wave or a sine wave, and the specific waveform depends on the design 

and manufacturing process of the module.

Response time: The response time of a discrete output module is an important parameter to 

measure its performance. The shorter the response time, the faster the module responds to 

the control signal, and the better it can meet the requirements of real-time control.

Accuracy and error range: The accuracy and error range of the discrete output module are 

also important technical parameters. Generally speaking, the smaller the accuracy and error 

range of the discrete output module, the better its performance and the more accurate the 

control effect.

Working environment conditions: The working environment conditions of the discrete output 

module include working temperature, humidity, vibration, etc., which will affect the performance 

and service life of the module. Therefore, when choosing and using discrete output modules, 

it is necessary to take into account their working environment conditions.

Communication interface and protocol: The discrete output module usually has a communication 

interface and protocol, which can be used for data transmission and control with the upper 

computer or other controllers. Understanding and familiar with the communication interface and 

protocol of the discrete output module is helpful to realize better interconnection with other devices.

Protection function: Discrete output modules usually have protection functions, such as 

overcurrent protection, overvoltage protection, undervoltage protection, etc., to ensure the safe 

operation and service life of the module. Understand and be familiar with the protection functions 

of discrete output modules to help avoid damage or accidents due to unexpected circumstances.

The above are some common technical parameters of discrete output modules, according to the 

specific application requirements and scenarios, there may be other technical parameters to 

consider. When selecting and using discrete output modules, it is recommended to read the product 

manual carefully and understand the relevant technical parameter requirements.


 

Discrete output modules have the following advantages in the application of control systems:


Precise control: The discrete output module can accurately control the controlled object, 

and achieve high-precision adjustment and fast response by configuring the output channel 

and the corresponding control algorithm.


Multiple output types: Discrete output modules support a variety of output types, such as 

dry contact, transistor and SSR (solid state relay) outputs, to meet different control needs.


Isolation protection: The output part of the discrete output module is completely isolated from 

the control logic part, which helps to enhance the anti-interference ability and reliability 

of the system.


Easy integration: The discrete output module has a variety of communication protocols and 

interfaces, and can communicate with various controllers and host computers to achieve data 

transmission and control, and is easy to integrate into the existing control system.


Easy to configure and program: Discrete output modules usually have a simple user interface 

or dedicated software, and users can easily configure various parameters of the module to 

achieve fast programming and debugging.


However, discrete output modules also have some disadvantages:


Higher cost: Discrete output modules are typically designed with industrial-grade components 

and circuits, making them more expensive and unsuitable for low-cost applications.


Maintenance and repair inconvenience: discrete output module structure is more complex, 

maintenance and repair may require professional tools and technical support, inconvenient 

for on-site maintenance.


Accuracy is limited by the module itself: the accuracy of the discrete output module is limited 

by the accuracy of its internal circuits and components, and there may be certain errors relative 

to the analog output module.


In summary, discrete output module has the advantages of precise control, multiple output 

types, isolation protection, easy integration and easy configuration and programming in the 

application of control system, but it also has the disadvantages of high cost, inconvenient 

maintenance and repair, and limited accuracy by the module itself. In practical applications, 

it is necessary to select and use according to specific needs.
