Allen-Bradley 1769-PB4 Compact I Power Supply Module

Allen-Bradley 1769-PB4 CompactLogix power supply module provides both a 5 V DC logic rail and a 24 V DC I/O bus for Compact I/O modules in a 1769 rack. It accepts a 19.2–31.2 V DC input and delivers 5 V DC at up to 4.0 A and 24 V DC at up to 1.7 A, for a total maximum of 100 VA. Power is distributed to I/O modules on either side of the supply, supporting up to 16 modules in a chassis. This 1769-PB4 is designed for use with 1769-series I/O modules in CompactLogix systems, enabling a centralized, two-rail power architecture for compact automation racks. It carries an IEC temperature rating of T4, reflecting suitability for typical industrial environments.
