Product Description
Product: 3BDH000721R1 CAI10-2-PEx – ABB Symphony Plus Explosion-Proof Analog Input I/O Module
ABB 3BDH000721R1 (CAI10-2-PEx) | Intrinsically Safe Analog Input Module for Hazardous Area DCS Control System
3BDH000721R1 CAI10-2-PEx is an intrinsically safe explosion-proof analog input I/O module launched by ABB, belonging to the Symphony Plus DCS control platform. The suffix PEx represents intrinsic safety certification, specially designed for flammable and explosive hazardous process sites. It collects standard 4–20mA analog signals from field transmitters such as pressure, flow, temperature and liquid level sensors, converts analog signals into high-precision digital data and transmits to the main controller through rack backplane bus. With full intrinsic safety isolation circuit design, it can directly connect field instruments installed in Zone 0/1 hazardous areas, realizing real-time monitoring and closed-loop control of process parameters in petrochemical, oil & gas and chemical plants.
