Q1: Shin wannan module yana tallafawa fitar da ƙarfin lantarki (voltage outputs)?
A1: A’a, 1769-OF8C an ƙera shi ne musamman don fitar da siginar ƙarfi (current outputs) 0–20 mA/4–20 mA. Idan ana buƙatar fitar da siginar voltage, a duba 1769-OF8V.

Q2: Ana buƙatar wutar waje ne don madaukai (loops)?
A2: I, ana buƙatar tushen wutar 24V DC da mai amfani zai bayar don ciyar da da’irar fitar da siginar analog da madaukai na current.

Q3: A wane sauri module ɗin zai iya sabunta duk tashoshi 8?
A3: Module ɗin yana da saurin maida sigina 5 ms ga dukkan tashoshi takwas a lokaci guda, wanda ke ba da kusan amsa ta ainihi (near-real-time) ga madaukar aikin sarrafa tsari.
