Allen-Bradley 1794-PS13 Flex IO Power Supply Module

Allen‑Bradley 1794‑PS13 FLEX I/O Power Supply Module delivers a regulated +24 VDC output capable of 1.3 A from an 85–264 VAC input, powering FLEX I/O adapters and modules in a Rockwell Automation FLEX I/O distributed I/O system. It provides about 31.2 W of output and can feed up to four FLEX adapters depending on load. The input range is 85–264 VAC (47–63 Hz) with typical input currents around 0.62 A at 120 VAC and 0.42 A at 230 VAC. The DC output is regulated to 20.4–27.6 VDC (±15%), including noise and up to 5% AC ripple. A green LED indicates healthy output within the 20.4–28 V range. Protection features include overcurrent trip at about 1.4 A and internal overvoltage limiting to 40 VDC; input-to-output isolation is rated at 2,500 V DC for safety. The module uses a terminal base for wiring (torque 0.8 N·m; accepts 22–12 AWG, 75°C insulation) and features an open‑style enclosure suitable for panel or cabinet mounting. Its compact dimensions are approximately 6.9 cm square by 8.7 cm tall, and it weighs around 2 kg. As part of the FLEX I/O family, the 1794‑PS13 is designed to supply backplane power to FLEX adapters and I/O modules in a localized installation, simplifying field wiring by combining power and I/O in a single modular backplane.
