5069 Compact guardlogix question

[Rsflipflop256]

Hi,

I am trying to spec out a system and the customer is asking for compact guardlogix, and they have a 120VAC control environment.

I am looking through proposalworks and cannot for the life of me find any 120VAC input cards in the compact guardlogix section.

What am I missing here? What is the safety solution for analog signals for compactlogix?

Thank you in advance.

You'll have to use some interposing relays and convert the signals to 24v dc.

I've never seen 120v AC analog signals before.

I think we're either missing some context or you've misspoken with some parts of your original post.

120VAC digital input modules are available for the 5069 platform: 5069-IA16
Analog input modules are available for the 5069 platform: 5069-IF8 (plus some other specialty AI modules)
Safety digital input and output modules are available for the 5069 platform: 5069-IB8S and 5069-OBV8S respectively
As far as I can see, safety analog input modules are not yet available for the 5069 platform.

If you need safety analog inputs, you may have to either install a 1734-AENT with a 1734-IE4S, or use an on-machine guard I/O block like the 1732ES-IB8XOBV4. Both of these would be compatible with your 5069 compact guardlogix safety controller.

You may have possibly confused “analog” and discrete “AC” signals. If not and you are actually looking for VAC analog inputs, they don’t exist.

You also won’t find VAC safety I/O. It’s 24VDC only.

“120VAC control environment” could mean a few different things.
1) 1-phase 120VAC mains, 24VDC field I/O
2) 1-phase 120VAC mains, 120VAC field I/O

Which is it?

In either case a 24VDC power supply is required for the controller/MOD power bus.

In the latter, as said above, interposing relays are needed. Probably safety-rated, too. All that plus wiring and cabinet upsizing to accommodate may dwarf the cost of just getting 24VDC field I/O from the start. You also won’t be doing analog inputs without 24VDC.
