Hello,
We are designing a SLC to ControlLogix replacement and running into some possible issues with output modules.
Current system uses 1746-OX8 modules and switches field loads (primarily 120VAC directly. The contact ratings on the 1746-OX8 are 2A per contact.
If we are reading correctly, the 1756-OW8 and 1756-OW16 have contact ratings of 1A per contact.
So far we've not found a 1756 relay ouptut module that retains the 2A per contact rating.
It is not very practical for to verify each and every actual load current and not practical to install interposing relays in the existing cabinets.
Has anyone experienced this same or similar issue? Suggestions?
Thanks.
