1. Product Overview
The ABB UFC721AE101 (Ordering Code: 3BHB002916R0101) is an 8-channel differential analog input module (ADCVI) belonging to the UFC700 series, seamlessly integrated with ABB AC 800M controllers and DCS 800xA distributed control systems. As a core component for industrial analog signal acquisition, it achieves high-precision conversion and isolation of standard industrial current (4-20mA/0-20mA) and voltage (0-10V/1-5V) signals, with 16-bit resolution and ±0.1% FS accuracy, and 1500V AC isolation performance to eliminate ground loop interference and electrical noise in harsh industrial environments. Equipped with redundant 24V DC power input and comprehensive fault protection functions, it is an ideal choice for critical process control scenarios in power generation, oil & gas, petrochemical, chemical and other industries that require high-precision and uninterrupted signal acquisition.
