FlexLogix Power Supplies
In a FlexLogix system, select an Allen-Bradley power supply. In applications that must be compliant with CSA requirements, use a Separated Extra-Low Voltage (SELV) power supply that is compliant with IEC 61010.1, Annex H.
When selecting power supplies, follow these guidelines.
- Provide power for the controller separately from the power for the FLEX I/O modules. To provide power for FLEX I/O modules, follow the guidelines in the documentation for those modules.
- When providing power for the 1794-FLA extended-local I/O adapter, treat the adapter as a communication adapter, not as an I/O module.
