Order now the 1794-PS13, a high-efficiency 1.3 Amp power supply module specifically engineered to provide regulated 24V DC power to Allen-Bradley FLEX I/O systems. This module is essential for maintaining consistent voltage levels across your distributed I/O nodes, ensuring reliable performance of sensors and actuators.
What Is the 1794-PS13?
The 1794-PS13 is a dedicated power supply module within the FLEX I/O product line. It converts an AC input (120V or 220V) into a steady 24V DC output. Its primary role is to power the FLEX I/O communication adapters and the attached I/O modules. The 1794-PS13 is designed to mount on a standard DIN rail alongside the I/O rack, providing a clean, compact power solution that eliminates the need for bulky external industrial power supplies in small-to-medium scale automation panels.
Key Technical Specifications
- Input Voltage: 85-264V AC (Universal Input)

- Output Voltage: 24V DC Nominal
- Output Current: 1.3 Amps maximum
- Inrush Current: 30A for 2ms
- Isolation Voltage: 250V (continuous)
- Mounting: Horizontal or Vertical DIN rail
- Operating Temperature: 0 to 55 Celsius
Application and Mounting Architecture
The 1794-PS13 is typically used to power a single FLEX I/O «bank» consisting of an adapter and up to eight modules. Because industrial environments are prone to power fluctuations, the 1794-PS13 features built-in overvoltage and overcurrent protection to safeguard the delicate electronics of the I/O modules. Its architecture is optimized for low heat dissipation, which is critical when mounting multiple power supplies in a closed enclosure with limited airflow.
Installation Advice
When wiring the 1794-PS13, ensure that the AC input leads are kept separate from the DC output leads to prevent EMI coupling. It is best practice to use a dedicated circuit breaker for the AC input. If your system configuration requires more than 1.3A of field-side power for sensors, do not attempt to daisy-chain the DC output of this module; instead, upgrade to the 1794-PS3 or use a separate bulk power supply for the field devices while using the PS13 strictly for the FLEXBus.
Frequently Asked Questions
Q: Can the 1794-PS13 power an entire rack of 8 analog modules?
A: It depends on the total current draw of the modules. You must calculate the sum of the FLEXBus current and field-side power. For heavy analog racks, the 1794-PS3 (3A) is often a safer choice.
Q: Does the 1794-PS13 support 220V AC input?
A: Yes, it is a universal input supply and will automatically handle any voltage between 85V and 264V AC without any jumper changes.
