Problem with IO Dry Contact module

Hallo all

We have a problem with I/O and I think I know why but need your confirmation.

if we connect the I / O module with the BASE-WIRED and an additional sensor, the I / O module hangs up irregularly.

If we connect the I / O module to the BASE-WIRED without an additional sensor but use a cable length of more than 3 meters for the DRY contacts, it can also happen that no status is recognized

If this is so correct, we can actually only use the I / O module in connection with a BASE-Wired and a maximum length of 3 meters, without an additional sensor

Hello, what sensor did you use together with the IO? Are you using PoE too?

we use one Temp Sensor and with PoE

helllo mmossner,
You may also check the connection of the RJ45 cable connected from your IO Sensor to your Base Unit.
I have tried to set up a wire on one of the IO dry contact inputs with more than 3-meter length and short the end of the wire and I can see the trigger response on the IO Sensor. You may also try to set the sensor polling time to 1 second.
