The 6 Analog Input (AI) module provides six 4-20 mA analog inputs. Each of the inputs, plus ground, are opto-switched into a precision A-to-D converter; ground is measured so short-term drift may be canceled. Simply put, there are 4000 steps over the total ±20 mA range with 40% (1600 steps) of the total range in active use (see also the 8AI section in the MOSCAD System Planner.) The 24 Vdc wetting voltage may be used to power the analog loops provided that isolation between the DI, AI, and AO circuits is not required. The module utilizes plug-in screw terminal wiring connectors. Availability: Usually ships in 6-8 weeks.
