GRV-IDC24 Inputs Failing

[amhaziq]

I have the same problem and it occurs at multiple site. I got this problem since 2021 till 2024. Changing channel and module.

One of my previous post.

GRV - IDC - 24 Faulty channel

I have a few 24VDC digital input to the DI module channel. After energize 8-10hour, the channel will become faulty, means not getting reading in EPIC. I already change to another DI module and same module with diff channel but same problem persist. I suspect my wiring got problem but I already check and my DI reading is 24.08VDC. What cause faulty channel to occur? High current?

Hope installing suggested diode can eliminate these problem
