Allen-Bradley 1747-BA Power Supply | 24V DC, 3A, SLC 500 Chassis, PLC Power Module

Allen-Bradley 1747-BA Power Supply | 24V DC, 3A, SLC 500 Chassis, PLC Power Module

Allen-Bradley 1747-BA DC power supply specifications. 24V DC, 3A output, for SLC 500 chassis. Power module for PLC systems, DIN rail mount, Rockwell Automation.

Product Overview

The Allen-Bradley 1747‑BA is a 24V DC power supply module designed specifically for the SLC 500 series programmable logic controller chassis. It provides regulated DC power to the SLC 500 backplane and connected I/O modules, replacing the need for a separate external power supply. It is a direct, chassis-integrated solution for powering SLC 500 control systems.

Technical Specifications

Key Features

• Integrated Power Solution:​ Designed specifically for SLC 500 chassis, providing reliable backplane power.

• Dual Input Voltage:​ Switch-selectable 120V AC or 240V AC input for global application flexibility.

• Regulated 24V DC Output:​ Provides a stable 3A, 24V DC power source for the CPU, I/O modules, and other chassis components.

• Slot-Based Mounting:​ Occupies one slot in the SLC 500 chassis, simplifying installation and saving panel space.

• Diagnostic LEDs:​ Features two LEDs for quick status indication: AC Power ON and 24V DC OK.

• Built-in Protections:​ Includes overload, over-voltage, and short-circuit protection for enhanced system reliability.

• High Power Capacity:​ 3A output is sufficient to power a fully loaded chassis and connected devices.

Applications

• Primary or supplemental power source for SLC 500 programmable logic controller systems.

• Providing chassis backplane power for SLC 500 CPU and I/O modules.

• Powering SLC 500 systems in industrial automation, manufacturing, and process control applications.

• Replacing external power supplies for a cleaner, integrated panel layout.

Important Notes

1. Chassis Compatibility:​ Only compatible with SLC 500 series 4, 7, 10, and 13-slot chassis. It cannot be used as a standalone power supply.

2. Power Budgeting:​ The total current draw of all modules in the chassis (CPU, I/O, communication) must not exceed the 3A output capacity of the 1747‑BA.

3. Input Voltage Selection:​ The input voltage selector switch must​ be set correctly (120V or 240V) before applying power to prevent damage.

4. Heat Dissipation:​ Ensure adequate ventilation around the chassis, as the power supply generates heat during operation.

5. Replacement Part:​ This module is a common replacement part for legacy SLC 500 systems. Verify system requirements before specifying.
