Hello, I have a couple of inquiries:1- Is it possible to utilize the 1756-IA16/A module with TTL inputs? Can it work with both sourcing (PNP) and sinking (NPN) configurations?2- What significance does the "/A" in the part number of the module hold?
The 1756-IA16 is a Module with 120V AC Input that is part of Series A. If you are looking for a compatible module, refer to the specifications of the module. In the event of new hardware being introduced, subsequent versions will be denoted by Series B, C, and so on, typically due to component obsolescence.
Thank you for your input plvlce and apologies for the error in my previous message. I actually meant to refer to the 1756-IB16 DC input card, not the AC input card I mentioned before. Now that we have cleared up the version question, I have a new query: Can the 1756-IB16 DC input card be used with TTL inputs? Is it compatible with both sourcing (PNP) and sinking (NPN) configurations?
For more information, you can visit the Rockwell Automation literature page and access the document at the following link: https://literature.rockwellautomation.com/idc/groups/literature/documents/td/1756-td002_-en-e.pdf. Navigate to page 41 for specific information.
For information on voltage values and compatibility with TTL inputs, refer to page 41 of the manual linked in post #2. To ensure proper switching, a 1756-IG16 is required, where low equals true and high equals false.
In order to ensure compatibility with TTL inputs, it is recommended to use a 1756-IG16 module, despite its low = true and high = false configuration. However, an alternative option is to simply utilize an Exclusive Or operation to toggle the bits if dealing with inverted inputs is not desired.
Hi there! For your first question, yes, the 1756-IA16/A module is not restricted to just TTL inputs; it is versatile and it can efficiently operate with both sourcing (PNP) and sinking (NPN) configurations. For your second query, the "/A" suffixed to the module part number represents a revised or updated version of the original, so it essentially highlights an upgrade or modification to the product attributes, features or functionalities.
Hi there! To answer your first query, no, the 1756-IA16/A is not compatible with TTL inputs. It’s suited for a range of 10-31.2 V DC. For the second question regarding sourcing and sinking, yes, this module can work with both configurations, PNP (sourcing) and NPN (sinking). Regarding the "/A" in the part number, it typically denotes a revision level of the product. This means there could be design improvements or minor changes when compared to the base model (without the "/A"). Hope this clears things up for you!
Hello, for your first question, the 1756-IA16/A is a digital AC input module, it's not designed for TTL inputs. It operates with AC signals, not DC, hence it isn't compatible with either sourcing (PNP) or sinking (NPN) configurations. As for your second question, the "/A" in the part number typically signifies a revision level. Manufacturers use this to indicate updates or changes to the original design of the part. Hope this helps!
