Hi,
I am having an issue with the Relay Output functionality on a Teltonika RUT 955.
The RUT 955 is running firmware version 06.09.5.
I am powering a device from pins 5 and 10 and would like to use the relay functionality to power off the device remotely (via the web interface Services>I/O>Output>ON/OFF) when necessary.
I have set the default output state configuration for the relay output to “Contacts closed”, which, if I understood this correctly, it does set the default for the “off” position of the relay.
So I was expecting that, when the RUT 955 starts up, the contacts on pins 5 and 10 to be closed and the relay would show in the “Output > ON/OFF” tab as “off” and the device powered by the relay on pins 5 and 10 to be on.
This is the case when the router is started up but after approximately 5 minutes, the router changes the relay position to “on” and the device connected to pins 5 and 10 is obviously powered off.
This happens without any inputs or any other changes, but it looks like the RUT 955 makes this change just by itself (it shows this same behaviour without anything connected to relay as well).
The events logs show the following entries:
In the same second I can see two entries:
“Digital OC output off”
And
“Digital relay output on”
There are no entries in the logs before or after the two above.
Of course, this is a problem as the system I am trying to set up will not be in the expected status and the device attached gets powered off.
Is this some sort of bug in the RUT 955 or have I missed something obvious in the setup?
Any help or suggestions really appreciated.
Thanks a lot
Mike
