Best Isolated Modules for PLC Integration on 35mm DIN Rail - Recommendations Needed

Question:

Hello Team, I am currently employed as a Hardware Design Engineer at Dover Corporation, where we utilize PLC communication as the primary interface for our products. Our PLC module of choice is from Automation Direct. Recently, one of our customers has requested Isolated Inputs and Outputs for our product. To accommodate this request, we are considering adding pre-made isolated modules to the existing PLC DIN rail. Could you please recommend any available Isolated Modules in the market that we can purchase for this purpose? Your input would be greatly appreciated. Thank you.

If you are utilizing AD PLCs, consider checking out the following products at Automation Direct: the KPR-SCE-24VACDC-1 electro-mechanical relay and the ZL-RRL16W-24-1 ziplink wiring solution. I have personally used ziplinks and found them to work effectively in my automation projects. Browse these items on the Automation Direct website for reliable and high-quality PLC components.

As a budding automation expert, have you explored the selection of AD PLC products available at AutomationDirect? I have found great success with their electro-mechanical relays, such as the KPR-SCE-24VACDC-1. Additionally, I have had positive experiences with their ziplinks, like the ZL-RRL16W-24-1 for wiring solutions. When it comes to PLC brands, I personally prefer Phoenix Contact or Rockwell. As my younger brother used to say, Rockwell may not be the cheapest option, but it certainly delivers quality. In the case of PLCs, investing in a reliable brand like Rockwell may be worth the extra cost. A helpful tip to keep in mind is to separate the outputs from your PLC by placing relays in one cabinet and inputs in another. This practice ensures that only circuits with zero volts are exposed in the field, maximizing safety and efficiency.

Hello! Yes, indeed, isolated modules can help manage different ground reference voltages and enhance overall system immunity. As per your request, I'd recommend the Siemens Simatic ET 200SP series which offers a wide range of isolate modules. However, another superb option to explore would be the distribution boards by Wago. Their 750 series can handle both isolated inputs and outputs really well, providing extra versatility. Please remember to double-check compatibility and wiring safety with your PLC system. Hope this helps!

Hi there! It's great that you’re looking to enhance your product with isolated inputs and outputs. One option you might want to consider is the Moxa IOLogik E1210 series, which offers robust isolation and is quite popular in industrial applications. Another excellent choice is the Schneider Electric Modicon series, which also provides well-designed isolated I/O modules that can seamlessly integrate with your existing PLC system. Be sure to check their compatibility with your current setup and the specific isolation levels you need for your application. Good luck with your project!

Hey there! For isolated I/O modules, you might want to check out the Opto 22 G4 line or the Phoenix Contact I/O system—both offer a variety of options that can easily integrate with your existing Automation Direct PLCs. They provide good isolation and are known for reliability. Just ensure they meet the voltage and current specs you need for your application. Hope that helps!
