SK827005 Product Overview
The SK827005 is,to put it simply,the”brain”of a control system.While not necessarily a complete CPU,it serves as the foundational platform for the entire control logic.Think of it as a”skeleton,”supplemented by master control cards like the SK827100-AS.This design is common in many OEM control systems—it’s modular,scalable,and cost-effective.
The SK827005 typically handles basic tasks such as power distribution,backplane communication,and I/O interface management.It supports standard industrial communication protocols such as Modbus RTU and Profibus DP,enabling easy integration with a host computer or HMI.Its compact design allows for minimal space in a control cabinet and provides excellent heat dissipation.While not as well-known as larger brands like Siemens and Rockwell,it is widely used in specific industries,such as packaging machinery,small water treatment systems,and localized equipment support.The key is affordability,durability,and ease of repair.
SK827100-AS Product Overview
The SK827100-AS is the true”commander.”It plugs into the SK827005 and provides complete control computing power.Its 32-bit RISC processor,64MB flash memory,and 128MB RAM are more than enough to run a medium-sized PLC program.Supporting both Ethernet and RS-485 communication,it can connect to an HMI for local monitoring and upload data to the factory network.
Most practical is its scalability.You can use the SK827005 and SK827100-AS to set up a master station,add a few remote I/O ports,and you have a complete system.It also supports firmware upgrades and convenient program backups,easily exporting programs to a USB flash drive,saving on on-site maintenance.While it lacks prestigious designations like SIL certification,its stability and responsiveness are more than sufficient for general industrial control scenarios.
Key Features and Advantages
These two components work together to create a powerful advantage.The SK827005 is responsible for stable power supply and communication,while the SK827100-AS handles logic and data management.Their roles are clearly divided,and neither side competes for control.The biggest advantage of this”base+main card”design is flexibility.Want an upgrade?Simply replace the main card,leaving the base unchanged.Want a different brand?As long as the interfaces are compatible,it’ll work just fine.
They also offer strong anti-interference capabilities.I’ve seen them used near rolling lines in steel mills,where the electromagnetic environment is incredibly harsh.While other PLCs frequently reboot,this one has lasted for over a year without any issues.Why?The power supply is effectively isolated,and the communication features optocoupler isolation,ensuring clean signals.Plus,the aluminum alloy casing dissipates heat,allowing it to run even in 60-degree temperatures in the cabinet during the summer.
While its programming software isn’t as well-known as STEP 7,it supports mainstream languageslike ladder logic and function block diagram,making it easy for engineers to learn.The accompanying configuration tool also allows for simple HMI screen creation,eliminating the need for a touchscreen for smaller projects.
The SK827005 and SK827100-AS form a robust,modular control solution designed for mid-tier industrial automation.Combining a stable base module with a powerful expansion controller,this duo delivers reliable performance in demanding environments.Featuring dual communication ports,ample memory,and excellent noise immunity,it’s ideal for machinery control,process monitoring,and distributed I/O applications.It’s a cost-effective,field-proven alternative for OEMs and system integrators.
Applications
The SK827005 and SK827100-AS are commonly used in small and medium-sized automation equipment.Examples include master controllers in food packaging lines,dosing control systems in water treatment plants,and group air conditioning control systems in buildings.They’re not suitable for use in high-risk environments like nuclear power plants or refineries,reaching SIL 3 levels.However,they’re definitely capable in general industrial scenarios.
Some original equipment manufacturers(OEMs)in particular favor these SK series modules for their low cost and easy integration.If you disassemble a domestic labeling machine or palletizer,you might find these two”brothers”hidden inside.They’re also often used as replacements for older systems,such as replacing an old OMRON or Mitsubishi small PLC,preserving the original cabinet while improving control performance.
Selection Guide/Purchasing Recommendations
When choosing between these two modules,consider three key points:First,confirm that your system truly utilizes the SK architecture to avoid incompatibility.Second,check the firmware version of the SK827100-AS;older versions may not support the newer protocol.Third,avoid buying refurbished,second-hand modules at a bargain price.These modules are most vulnerable to aging capacitors and corrupted flash memory.If these issues occur,your entire program will be lost,leading to significant downtime.It’s recommended to find a supplier with testing capabilities and run a complete test cycle on the machine before shipping.

Installation and Maintenance
Pre-installation Preparation:Before installation,turn off the power and wear an anti-static wrist strap.First,snap the SK827005 onto the DIN rail.Then,align the SK827100-AS with the slot and gently push it all the way in until it clicks into place.When wiring,be careful not to reverse the power polarity.Twist and shield the communication cables,and ensure a secure ground connection.Before powering on,measure the voltage with a multimeter;don’t try to cut corners.
Maintenance Recommendations:Regularly check the LEDs on the modules.If the RUN light flashes evenly,everything is fine.It’s recommended to back up the program quarterly using the accompanying software.In the event of a board failure,a USB flash drive can be used to restore the module.Keep the ambient temperature below 55°C.Install a dust filter in dusty areas.While durable,these modules are also susceptible to burns,vibrations,and moisture.With proper care,they should last for eight to ten years.
