Description

The Allen-Bradley 1746-P7 is a specialized DC-input power supply module designed for use with the SLC 500 controller platform. This module is engineered to provide reliable, regulated power to the SLC backplane, supporting the processor and associated I/O modules in environments where standard AC power is not available or practical. It is particularly well-suited for applications involving remote telemetry units (RTUs), automotive testing rigs, and battery-backed industrial control systems.

Features

  • Designed specifically for the Allen-Bradley SLC 500 chassis.
  • Accepts a flexible input voltage range of 10–30V DC.
  • Output capacity scales based on the input voltage (12V or 24V DC).
  • Provides stable, regulated power to the backplane to ensure consistent controller operation.
  • Compact, modular design for easy integration into existing 1746 chassis configurations.

Applications

The 1746-P7 is ideal for mobile or remote industrial installations, including:

  • Remote Telemetry Units (RTUs) operating on battery or solar power.
  • Automotive and vehicle-based testing and data acquisition rigs.
  • Emergency backup systems where DC power is the primary or secondary source.
  • Industrial control applications requiring isolation from AC power fluctuations.

Installation Guidelines

  • The 1746-P7 must be installed in the far-left slot of the 1746 chassis.
  • Ensure all power is disconnected from the chassis and the DC source before installing or removing the module.
  • Verify that the DC input source is within the specified 10–30V DC range before applying power.
  • Ensure proper grounding of the chassis to minimize EMI and protect against electrical surges.
  • Maintain adequate clearance around the module to allow for proper ventilation and heat dissipation.
  • Use appropriate wire gauges for DC input connections to minimize voltage drop.

FAQ

Does the 1746-P7 work with AC power?

No, the 1746-P7 is strictly a DC-input power supply. It is designed to convert 12V or 24V DC input into the regulated power required by the SLC 500 backplane.

Can I use this module in any slot of the chassis?

No, the 1746-P7 is designed to occupy the far-left slot of the 1746 chassis, which is the dedicated power supply slot for the SLC 500 system.

How does the input voltage affect performance?

The output capacity of the module is dependent on the input voltage. Operating at 24V DC provides higher efficiency and greater power capacity compared to operating at 12V DC.
