The 1756-PAR2K is a redundant power supply component manufactured by Rockwell Automation for its ControlLogix Programmable Automation Controller (PAC) platform. It is designed to provide reliable and fault-tolerant power to your ControlLogix system.
Features:
The 1756-PAR2K consists of two internal power supplies and add-ons that provide redundancy. This means that if one power supply fails, the other can continue to power the ControlLogix system, minimizing downtime and ensuring critical processes can continue to run.
Here are some of the main advantages of using a redundant power supply such as the 1756-PAR2K:
Increase system uptime: Redundancy helps minimize the impact of power failures and ensures that your ControlLogix system stays up and running most of the time.
Increased reliability: With backup power, you can improve the overall reliability of your ControlLogix system.
Reduced downtime: If a single power failure occurs, the redundant design helps minimize downtime for system repair or replacement.
Main features:
Dual power supply: Consists of two internal power supplies, typically 1756-PA75R models, each capable of providing 75 watts of DC power.
Automatic switching: If one power supply fails, the system automatically switches to a working power supply to maintain power to the ControlLogix chassis.
Status indicators: May have LED indicators that provide visual cues about the status of each power supply (on/off, potential failure).
Conformal coating: Some variants of 1756-PAR2K May have conformal coating to provide additional protection in harsh environments.
Applications:
The 1756-PAR2K is ideal for applications where high system availability and reliability are critical. Here are some examples:
Mission-critical manufacturing: Production lines that are down due to power failures can be very expensive.
Process control systems: Industrial processes that rely on continuous and uninterrupted operation.
Infrastructure Management systems: Building automation systems where reliable power is essential for critical equipment such as HVAC and security systems.
