24VAC from a 120VAC output card.

[jrhpuuk123]

Hello all,

I have a relay timer connected to an Allen Bradley 1756-OA16I output card. The output was on, but instead of getting 120VAC we only had 24VAC at the timer. All the other energized outputs from that card had 120VAC. I moved the timer to another available output and the issue was resolved. I haven't been able to find an explanation as to why that would be the case and I would love some insight. Thank you for your help!

Probably a duff output triac on that channel.

What is the supply voltage(value) to that output?
