Most Popular I/O Ports Made For Industrial Computing Applications

As IoT, Big Data, and Machine Learning advancements place increased demands on industries like manufacturing and automation, data and its value continue to spread between IT and OT efficiencies. More and more gadgets are being connected to machines in this era of change, dubbed “industry 4.0,” putting immense demand on computing systems to be versatile in their specific duties and workload performance. Industrial computers, for example, are now used as platforms for local or edge workload aggregation and convergence. In other words, industrial computing systems must now be able to handle a wide range of data inputs that send critical data for real-time decision-making. As a result, industrial computers are compatible with a wide range of legacy and modern input and output (I/O) ports.


Various inputs and outputs ports are:

  • Serial Ports
  • Video Ports
  • USB Ports
  • Local Area Network (LAN) Ports

Serial ports

Serial ports are one of the most common ports in both industrial computers and traditional computers. Serial ports are designed to make communication with the legacy devices in the industry. It doesn’t allow faster communication however it is considered the most reliable protocol. Depending upon the applications and devices connected, serial ports have three different function modes such as RS-232/422/485.

Video ports

Video ports are very essential to display the output from the various processes in industries. The most common video ports are VGA, DVI, HDMI, and DP.

VGA ports are used to connect with the legacy devices due to VGA uses analog signals instead of digital signals.

DVI, HDMI, and DP are the most modern video ports and it provides very high resolution as well as refresh rates but it can’t connect with the legacy devices


DIO/GPIO stands for digital I/O and general-purpose I/O. These are types of an interface that are designed to perform various electrical devices and sensors that don’t have a common interface. DIO/GPIO uses digital signals usually represented as either ON or OFF. Due to this feature, we can use the industries where many ON/OFF signals need to be transmitted. This can also be used in alarm sensors.

USB ports USB ports are considered as a standard port for a wide variety of devices that required more bandwidth increases, which is just not supported by the serial port. We can connect multiple USB devices without overconsuming power and we can also keep devices in idle when not in use.

Local Area Network (LAN) ports

LAN ports are designed to make a wired connection with the speed up to GbE per port. LAN ports are mainly used to connect computers with modems, switches, routers to make both uplinks and downlinks to transfer data.

Why industrial PC is required?

We know that industrial PCs are specially designed to use for industrial process. We can’t use normal PCs in industrial areas due to the condition of plants. Usually, PCs in almost all industries are working under various circumstances like humidity, temperature, dust particles, liquids, etc.

The computer’s worst enemies are vibration, shock, temperature, dust, etc. Normal PCs are not designed to work on the above-mentioned conditions. Industrial PCs are capable of working 24/7, in hot, vibration conditions.

Process control and/or data acquisition are the primary functions of industrial PCs. Industrial PCs may use to control other computers in the plants in a distributed processing environment.

What are the specifications of an industrial PC?

The specification of industrial PCs is a very highly sensitive display and some models come with a touch screen.

In industrial environments, vibration, dust, high heat and cold, air pressure, and humidity create unstable circumstances so the industrial PCs have various IP ratings to protect from the above-mentioned issues.

Most of the industrial PCs come along with the graphic card for getting a high performance. Industrial PC runs on the Windows latest versions and some models are running based on various Linux OS.

Usually, industrial Pcs have two RAM slots for expanding RAM capacity and improving the performance of the system.
