Product Description

The 1746-P4 is an AC Input Power Supply. It is the most powerful unit in the SLC 500 power supply lineup, offering higher current output on the 5V DC and 24V DC backplane rails compared to the P1 or P2 models. This makes it the standard choice for large, fully loaded chassis or modules with high power consumption.

Product Parameters

Key Advantages

• High Power Density: Provides up to 10 Amps on the 5V rail, allowing for large configurations without needing multiple power supplies or smaller chassis.
• Internal Protection: Features built-in overvoltage protection and short-circuit protection to safeguard expensive CPU and I/O modules.
• User 24V DC Terminals: Includes an auxiliary 24V DC output terminal to power small external devices like sensors or small HMI panels directly.
• Reliability: Known for extreme durability in harsh industrial environments with a long mean time between failures (MTBF).

Usage Precautions

• Jumper Setting: Critical! You must manually set the input voltage jumper to match your local power source (120V vs 240V). Applying 240V while the jumper is set to 120V will likely destroy the unit.
• Heat Dissipation: Due to its high power output, ensure the cabinet has adequate ventilation. Do not block the cooling vents on the top or bottom of the module.
• Grounding: Ensure a solid connection to the functional earth (ground) terminal to minimize electrical noise and ensure safety.
• Loading Balance: While it has high capacity, always calculate the total current draw of your specific I/O modules using the SLC 500 selection guide to ensure you don’t exceed the 10A limit.

Product Applications

The 1746-P4 is typically found in:

1. Complex Manufacturing Lines: Where a 10-slot or 13-slot chassis is fully populated with high-density I/O.
2. Legacy System Support: Maintaining and upgrading existing SLC 500 installations in automotive or food & beverage plants.
3. High-Power I/O Mix: Systems utilizing many analog or specialty modules (like high-speed counters) that draw significant backplane current.
