Posted 7 Jan 2019 What Is Meaning Of Universal Analog Input Card? Share this post Link to post Share on other sites
Posted 7 Jan 2019 That usually means that the card can take multiple types of analog inputs. For example, it could take +/- 10VDC, 0-10VDC, 0-20mA, 4-20mA, thermocouple (multiple styles) or RTD. The card would usually have some hardware configuration (different terminals to select the type of input) and software configuration for scaling. Share this post Link to post Share on other sites

Posted 11 Feb 2019 (edited) It is not just a marketing term, there is a true functional difference between a dedicated function analog input card (4-20mA only) and a universal input card. An analog input card that takes a direct RTD or thermocouple input in addition to 0-10Vdc and 4-20mA has a lot of functionality that an analog input card that a 4-20mA-only card does not have.

Posted 16 Feb 2019 There is usually something it doesn't do. It's a good practice to read the specs before you put it in the submittals. Share this post Link to post Share on other sites

That's best practice regardless of the module you're specifying. Whenever I see brochures touting "Universal" anything I'm reminded of a cartoon I saw many years ago. It was a picture of an "Acme Universal Processor" featuring a two-position selector switch. The positions were labeled "Food" and "Word". Share this post Link to post Share on other sites
