Do you have a preferred 4-20mA isolator for your industrial needs? I have multiple flow meters and scales sending out 4-wire 4-20mA signals that I want to isolate before they reach my analog input card. Is isolation truly necessary for optimal performance? My specific card is a 5069 IF8.
I was recently introduced to the PR Electronics Universal Transmitter by one of my clients. This cost-effective device is versatile, accommodating various inputs and offering multiple outputs. It can also be personalized to suit different ranges. Additionally, there is an option with a relay output, which can be configured to activate at a specific setpoint.

Ken Moore mentioned using isolators from Moore Industries, known for their durability and SIL rating. I also utilized Moore Industries isolators to convert 0-1mA signals to 4-20mA for a PLC, allowing me to easily interface with an induction heater. These isolators have been operational without any issues since 2016. Find out more about these reliable isolators at Moore Industries' website.
Dale87 inquired about the best 4-20mA isolator for multiple flow meters and scales with 4-wire connections. Isolating the signals before reaching the non-isolated Analog input card, such as the 5069 IF8, is crucial for optimal performance. While isolation may not be mandatory if all instruments are already isolated, it is still recommended for smoother operation and protection against potential interference.
Isolation is indeed necessary for optimal performance as it provides protection against surges, electrical noise and ground loops, improves signal quality, and provides safety in case of a fault. Personally, I've had great success with isolators from Phoenix Contact - they handle a wide range of input/output configurations and provide reliable isolation. However, what's best really depends on the specifics of your setup and the environmental factors in your facility. Always remember to account for these aspects when choosing an isolator.
From my personal experience, isolation becomes extremely important when dealing with any kind of signal transmission in an industrial environment. Without it, you can run into problems like ground loops, which result into inaccurate readings. Some of my favorite 4-20mA isolators are from Pepperl+Fuchs and Phoenix Contact. However, double check the compatibility with your 5069 IF8 input card. It’s always best to go with something that's not just compatible, but also has excellent reviews in terms of form, function, and reliability.
