Local inputs floating?
« on: 2024-06-06, 18:51:31 »
I have had this issue before, but I think I finally found the real issue with my Webswitch 1216H.

The issue presents itself by toggling my local relays ON at seemingly random intervals. The issue affects relay 1 the most, but also affects relay 2 (less often)
I have Input 1 control relay 1 using the Auto Control Program.
I have input 2 control relay 2 using the ACP.
Disabling the ACP resolves the issue, but the obviously I can't control my relays with my switches.

For the purpose of troubleshooting, I disconnected the wiring connected to IN1, 0V and IN2. I then refreshed the inputs-page on the webserver and I can see that inputs are toggling between HIGH and LOW very frequently, almost on every refresh.

Measuring with a digital multimeter between IN1 and 0V I get 15,2VDC
Measuring with a digital multimeter between IN2 and 0V I get 15,4VDC

I can't see any fluctuation in the voltage while measuring, voltage seems stable, but I understand the my DMM wouldn't pick up short voltage drops.

I conducted the tests again with wiring to the switches in place this time, and I can see that toggling the switches indeed pulls the inputs from 15V to 0V (and back to 15V again since my switches pulse the inputs"

What voltage is expected on the inputs?
Could this be a software glitch? See my posts from a few years back: https://www.remoterig.com/forum/index.php?action=profile;area=showposts;u=2852
