Description

The Allen-Bradley 1746-P2 is a modular, rack-mounted power supply designed specifically for the SLC 500 programmable controller system. It serves as the primary power source for the chassis, converting AC line voltage into the regulated DC voltages required by the CPU, I/O modules, and communication adapters. This unit is engineered to provide stable power output, ensuring reliable operation of the controller even during minor fluctuations in the supply line.

Features

  • Designed for integration with SLC 500 modular chassis systems.
  • Provides 5V DC at 5A and 24V DC at 0.96A output capacity.
  • Selectable input voltage range: 85-132V AC or 170-265V AC (47-63 Hz).
  • Includes user-power current capacity of 200mA at 24V DC.
  • Maximum inrush current of 20A.
  • Supports up to two AWG wires per terminal for flexible field wiring.

Applications

  • Automotive Manufacturing: Reliable power for robotic welding and press control systems.
  • Food and Beverage Processing: High hold-up time capability to mitigate power sags during production cycles.
  • Pharmaceutical Production: Suitable for cleanroom-grade equipment such as centrifuges and autoclaves.
  • Water and Wastewater Treatment: Flexible voltage input allows for deployment in remote pumping stations.

Installation Guidelines

  • Chassis Placement: The 1746-P2 must be installed in the leftmost slot of the 1746 chassis.
  • Voltage Selection: You must manually configure the jumper terminal for the correct input voltage (120V or 240V AC) before applying power to prevent hardware damage.
  • Grounding: Ensure proper connection to the chassis ground terminal to minimize electrical noise and protect logic integrity.
  • Wiring: A maximum of two AWG wires per terminal is permitted.
  • Safety: Power down the system before inserting or removing the module from the chassis.

FAQs

What is the 1746-P2?

The Allen-Bradley 1746-P2 is a legacy, rack-mounted power supply for SLC 500 PLC systems, providing 5V DC (5A) and 24V DC (0.96A) power.

What are the input voltage settings for 1746-P2?

It supports dual voltage operation: 85–132V AC or 170–265V AC (47–63 Hz).

How do I configure the input voltage?

A jumper wire loop located near the AC input terminal block must be configured for either 120V or 220V operation before the unit is energized.

Can the 1746-P2 replace a 1746-P1?

Yes, it is a compatible replacement. The 1746-P2 provides higher output current (5A vs 3.6A at 5V) compared to the 1746-P1.
