1756-PC75-CC Allen Bradley

Description

Product Name:  1756-PC75-CC Allen Braley Input module

Product details:  

The Allen-Bradley 1756-PC75-CC is a high-performance, conformal coated power supply designed for the ControlLogix system. It is specifically engineered to provide 24V DC power to the chassis backplane, ensuring reliable operation of controllers and I/O modules in demanding environments.

## Product Overview

The “CC” suffix indicates that this module features a conformal coating, which provides an extra layer of protection against moisture, dust, and chemical contaminants. This makes it an ideal choice for heavy industrial applications where environmental exposure is a concern.

## Technical Specifications

## Key Advantages

• Enhanced Durability: The conformal coating protects the internal circuitry from “tin whiskers,” corrosion, and humidity, significantly extending the hardware’s lifespan in harsh conditions.

• High Efficiency: Optimized power conversion reduces heat dissipation within the cabinet.

• Seamless Integration: Designed for the standard ControlLogix 1756 chassis, allowing for “plug-and-play” installation.

• Robust Protection: Includes built-in overvoltage and short-circuit protection to safeguard expensive CPU and I/O modules.

## Important Considerations & Safety

• Chassis Compatibility: This power supply occupies the dedicated power supply slot on the far left of the ControlLogix chassis. It cannot be placed in a standard I/O slot.

• Heat Dissipation: Ensure adequate clearance around the chassis for airflow. Overheating can lead to a shortened lifespan or unexpected shutdowns.

• Wiring: Always use the recommended wire gauge for DC input to prevent voltage drops. Ensure the protective earth (PE) ground is connected properly to reduce EMI.

• Hot Swapping: While many ControlLogix modules are “Removal and Insertion Under Power” (RIUP) capable, the power supply itself should not be replaced while the input power is active to avoid arcing.

## Common Applications

The 1756-PC75-CC is widely used in industries where downtime is costly and environmental conditions are aggressive:

1. Oil & Gas: Offshore platforms or refineries where salt air or sulfurous gases are present.

2. Wastewater Treatment: High-humidity environments with exposure to corrosive chemicals.

3. Mining & Metals: Areas with high levels of conductive dust.

4. Food & Beverage: Facilities that require frequent wash-downs or have high humidity levels.
