ABB Redundant Power Supply Module IEPAS02 infi 90 AC System Power Supply Module Control Board
IEPAS02 Description
The ABB IEPAS02 is a modular power supply and I/O expansion module designed for ABB's industrial automation systems, including the 800xA, Network 90, and Infi 90 platforms. It serves as a critical component in DCS (Distributed Control System) and PLC-based control architectures, providing reliable power distribution and signal interfacing for industrial processes. The module integrates multiple voltage outputs (+5V, ±15V, 24V) and supports mixed I/O configurations (digital, analog, and specialized signals like thermocouples), enabling seamless connectivity between controllers and field devices such as sensors, actuators, and valves. Its robust design ensures stable operation in harsh environments, including extreme temperatures and hazardous areas, making it suitable for industries like oil and gas, chemical processing, and manufacturing.
