Description Reviews

Description

The Allen-Bradley 1746-P7 is a specialized DC-input power supply module engineered for the SLC 500 controller series. This unit is designed for environments where standard AC power is not available or where DC-based power architectures are required, such as in battery-backed systems, remote telemetry installations, or mobile industrial testing rigs. It provides stable, regulated power to the SLC 500 backplane, ensuring reliable operation for the processor and installed I/O modules.

Features

Supports a wide input voltage range of 10-30V DC, with nominal operation at 12V or 24V DC.
Dynamic power output capacity scaled based on input voltage (higher capacity at 24V DC).
Designed for integration into the standard SLC 500 chassis.
Integrated protection features to ensure system stability during power fluctuations.
Robust construction suitable for demanding industrial environments.

Installation Guidelines

Mount the 1746-P7 module exclusively in the far-left slot of the 1746 chassis.
Ensure the system power is disconnected before installing or removing the module to prevent electrical damage.
Verify that the DC input source meets the 10-30V DC requirement before connecting.
Maintain proper clearance around the chassis to allow for adequate ventilation and cooling.
Use appropriate wire gauges for the DC input terminals to minimize voltage drop.
Ensure the chassis is properly grounded in accordance with local electrical codes to mitigate EMI/RFI interference.

FAQ

What is the primary function of the 1746-P7?

The 1746-P7 serves as a DC-to-DC power supply for the SLC 500 rack, converting 12V or 24V DC input into the necessary voltages for the backplane components.

Can this power supply be used in any slot of the chassis?

No, the 1746-P7 must be installed in the far-left slot of the 1746 chassis, which is the dedicated power supply location for this controller system.

Does the output power change based on the input voltage?

Yes, the module's power output capacity is dependent on the input voltage. It provides higher wattage when supplied with 24V DC compared to 12V DC.
