Product Summary
The 1794-PS13 is a crucial power supply for Rockwell Automation Flex I/O systems. It accepts a wide AC input range of 85-264VAC. This module then provides a stable 24VDC output to power your I/O modules. Its robust design supports daisy chaining for up to four adapters. This unit ensures reliable system operation in demanding industrial environments.
Product Procurement & Buyer Guide
Understanding the Power Needs for Your Flex I/O System

The 1794-PS13 solves a critical pain point for control engineers. You need a reliable power source for distributed I/O. This module accepts global AC line voltages from 85 to 264VAC. It converts that power into a regulated 24VDC bus. This output powers your Flex I/O adapters and modules. The unit delivers a continuous output current of 1.3 Amps. It also provides a power surge to drive up to four adapters. This capability simplifies your system’s power architecture.
Key Specifications for Procurement Managers
When sourcing this part, verify the critical input and output ratings. The 1794-PS13 has a nominal input of 120VAC at 0.6 Amps. It also operates on 230VAC at 0.42 Amps. The maximum input current is just 0.7 Amps. Its output power is rated at 31.2 Watts. The module features overcurrent protection at 1.4 Amps. This protection safeguards your downstream I/O hardware. The unit’s power dissipation is only 7 Watts. This low dissipation helps manage cabinet heat loads.
Installation and Wiring Details

Proper installation is key for reliable performance. The 1794-PS13 has a compact open-type enclosure. Its dimensions are 87mm high by 69mm wide by 69mm deep. You must use solid or stranded copper wire for connections. The acceptable wire size ranges from 22 to 12 AWG. The insulation rating must be 75°C or higher. You need to apply a torque of 0.8 Nm to tighten all connections. The module also requires an isolation voltage of 2500VDC. This isolation protects between the AC input and DC output terminals.
Operational Environment and Safety
This power supply operates reliably in harsh conditions. Its operating temperature range is 0 to 55 degrees Celsius. The storage temperature range is -40 to 85 degrees Celsius. It also functions in 5 to 95% non-condensing humidity. The module has a built-in power indicator for easy diagnostics. The green LED energizes when the output voltage is between 20.4 and 28VDC. The light stays off when power is absent or the unit shuts down. Overvoltage protection internally limits the output to 40VDC. This feature protects your connected Flex I/O components from damage.
