E-HELP: Isolating Feedback on VFDs

E-HELP: Isolating Feedback on VFDs
Q: We are a boiler/burner company dealing with a rising amount of computer-based burner controls. We have installed several and have some blowers that are controlled by VFDs (Variable Frequency Drives). We have run into issues with noise on certain systems. We get occasional problems with 4-20mA feedback from the VFD despite going through the proper grounding techniques. We are wondering if installing an opto isolator on the feedback loop might eliminate our issue. We have used the SIX Signal Isolator many times on the signal going to the VFD to offset impedance issues on the VFD. Can we put an opto isolator on both signals?

Reliability Success Story: PTT Upgrade

Reliability Success Story: PTT Upgrade
The PTT, Potentiometer Transmitter, was in use at a large dam on a branch of the Colorado river as part of a system to deliver water and power via one of the largest public power utilities for consumers and businesses in the southwest since 1984. The facility has many PTTs in use today.
