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?

Which I/O module are you using, GRV-IDC-24 or GRV-IDCS-24

Both have a input range of 15-30VDC and need 2mA to work.

What is connected to your input channels?
How is it wired?
Are you checking in groov Manage for the status or in PAC Control/Codesys?

At page 9 of this document you will find the wiring diagram.

  1. GRV-IDC-24

  2. There are 24VDC Relay 2 Contact (Omron MY2N DC24). Iā€™m using normally open contact. When relay energize, 24VDC connected to contact input will send 24VDC to GRV-IDC-24. Everytime digital input channel energize for long time, no input signal detected at Groov although I can measure 24VDC at wiring input to DI module.

  3. DI signal not detected in LED indicator, groov manage and PAC Control.
