The 1756-PAR2XT is a redundant AC power bundle manufactured by Rockwell Automation for its ControlLogix Programmable Automation Controller (PAC) platform. It provides a reliable and fault-tolerant power supply with additional features compared to the standard 1756-PAR2K we discussed earlier.
Features:
The 1756-PAR2XT builds on the core features of the 1756-PAR2K, offering redundancy and a few additional benefits:
Dual power supplies: Similar to the 1756-PAR2K, it includes two internal power supplies, probably the 1756-PAXTR model, each capable of providing reliable power.
Automatic switching: When one power supply fails, the system automatically switches to a working power supply to maintain power to the ControlLogix chassis.
Extended temperature support: The 1756-PAR2XT May be designed for extended temperature environments compared to the 1756-PAR2K, potentially making it suitable for a wider operating range.
Main features:
Dual power supply (1756-PAXTR) : May include two 1756-PAXTR power supplies, which may offer features such as a wider operating temperature range or other improvements compared to the 1756-PA75R used in the 1756-PAR2K.
Automatic switching: Maintain uninterrupted power supply during 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 within the ControlLogix case.
Extended temperature support (potential) : The 1756-PAR2XT May be suitable for a wider operating temperature range than the 1756-PAR2K. Please refer to the specific documentation for confirmation.
Applications:
The 1756-PAR2XT is ideal for applications requiring high system availability, reliability and the potential to operate over a wider temperature range. 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, especially in harsher environments.
Infrastructure Management systems: Building automation systems, where reliable power is essential for critical equipment (HVAC, security), can operate in a variety of temperature conditions.
