PLD or PGA
(OP)
I am looking to create a logic circuit with no more than 20 gates. What would be better to use a PLD or PGA or something else? We are presently using a small PLC that is presenting alot of problems. Any more info would be appreciated. Thanks.

You're kind of standing there wanting to change from metal furniture to wooden furniture because the metal keeps getting bent up. All the while, not noticing the elephant standing next to you.
You need to hunt down why the PLC is freaking. Whatever it is, will be far more technical to deal with in any PLD/PGA replacement.
If you can get an isolated scope,(battery powered), and someone who knows how to use it. I suspect you will find the problem immediately and some minor change or an added EMI filter somewhere will completely remedy your problem.

For that matter, how do you even know if your PLC is programmed correctly?

AB 700 series relays.

For timing add a pneumatic timing head, 100 FPTA30

Scroll down a page.
We had a fire near a panel that melted some of the casting metal conduit hubs off the side of the panel.Some of these relays survived inside the panel.
Pneumatic timing is quite tolerant of electrical noise.
