- AC-powered FLEX I/O supply for nominal 120 or 230 V AC systems
- Accepts an 85…264 V AC input across the 47…63 Hz frequency range
- Provides external 24 V DC power up to the documented 1 A capacity
1794-PS1 supplies the external 24 V DC source used by legacy FLEX I/O adapters and connected modules.
Its wide AC input range supports nominal 120 or 230 V systems while the output remains limited to the documented 1 A capacity.
Do not parallel this power supply with another unit, and review downstream startup current and any controller-specific resistor requirement before energizing.
Availability, condition, price, and shipping time for 1794-PS1 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- The supply accepts the documented 85…264 V AC range at 47…63 Hz.
- Branch protection, disconnecting means, conductor rating, and grounding remain installation responsibilities.
- Measure the AC source under load rather than relying only on nominal system voltage.
- The 24 V DC output is rated for 1 A total user current.
- Include the adapter, I/O modules, startup demand, and cable loss in the load calculation.
- Do not wire two 1794-PS1 or related FLEX I/O supplies in parallel.
- Observe output polarity and the official adapter or controller connection diagram.
- Use the documented resistor when a 1794-PS1 supplies a FlexLogix controller.
- Verify output voltage and downstream status before reconnecting field devices.
- Providing 24 V DC power to compatible FLEX I/O adapters and their local modules.
- Supplying legacy distributed I/O assemblies from nominal 120 or 230 V AC sources.
- Powering documented FlexLogix controller arrangements that include the required output-side resistor.
