The 1756-PBR2XT is a redundant 19-32 VDC ControlLogix-XT power supply assembly manufactured by Rockwell Automation . It is designed to provide a reliable and fault-tolerant power supply for ControlLogix-XT PAC systems in harsh environments.

Here is a breakdown of the features, the main features, and where to find more information about the 1756-PBR2XT:

Features:

The 1756-PBR2XT builds on the functionality of the standard ControlLogix power supply to provide redundancy, thereby extending system uptime and reliability:

Dual power supply: It may include two internal power supplies, possibly the 1756-PAXTR model, each capable of providing DC power in the 19-32 VDC range.
Automatic switching: If one power supply fails, the system automatically switches to a working power supply to maintain uninterrupted power to the ControlLogix-XT chassis.
Extended temperature support: The 1756-PBR2XT is designed for ControlLoGIX-XT systems, which are built to operate in harsher environments than standard ControlLogix systems. This may mean that the power supply itself operates over a wider temperature range.
Main features:

Dual power Supply (1756-PAXTR potential) : May include two 1756-PAXTR power supplies, which may offer features such as a wider operating temperature range or other improvements compared to standard ControlLogix power supplies.
Automatic switching: Ensures continuous power supply during a power failure.
Status indicator: Provides visual cues about the status of each power supply (on/off, potential failure).
Case adapters: May include case adapters for installation in the ControlLogix-XT chassis.
Extended temperature support: Designed to operate over a wider temperature range than standard ControlLogix power supplies (see specifications for more information).
Tri-resistant paint: There may be conformal coatings on the circuit board to provide additional protection against dust, moisture, and other contaminants typically found in harsh environments.
