Installation & Integration Details
- Mounting: Designed for easy vertical or horizontal mounting on a panel or DIN rail.
- System Compatibility: Integrates with Allen-Bradley PLC systems using the built-in Remote I/O (RIO) interface.
- Wiring: All I/O and power connections are made to the module's integrated terminal blocks.
- Power Requirement: Requires a single 120V AC power source within the 85-132V AC range for module operation.
FAQ - Frequently Asked Questions
- What makes the 1791-24AR different from other 1791 modules? It uniquely combines 24 AC inputs with 8 general-purpose relay outputs that can switch AC or DC.
- Can I use the relay outputs to control DC solenoids? Yes, the relays are suitable for DC inductive loads like solenoids, following the specified DC current ratings.
- What is the nominal input current? The typical input current is 11 mA at 120V AC.
- Are the relay outputs isolated? The electromechanical relays provide physical isolation between the control circuit and the load.
