Information About 1756-PAR2
The 1756-PAR2 belongs to the ControlLogix power family and provides a complete hardware set for implementing redundant power in Series B ControlLogix chassis. Its two 1756-PA75R power supplies operate in parallel through the 1756-PSCA2 chassis adapter, enabling seamless failover if one supply becomes unavailable. The included 1756-CPR2 cables synchronize and interconnect the redundant supplies to maintain consistent output and status information. Typical usage involves mission-critical environments—such as process control, safety systems, and continuous manufacturing—where uninterrupted controller power is essential.
Key Features:
- Complete redundancy bundle: Includes dual power supplies, redundant cables, and chassis adapter.
- Wide AC input range: Operates from 85–264 VAC with nominal ratings of 120/240 VAC.
- 75 W output capability: Provides stable power for ControlLogix backplanes up to 60 °C.
- Multiple output voltages: Supports 1.2 VDC, 3.3 VDC, 5.1 VDC, and 24 VDC rails.
- High insulation rating: 250 V continuous isolation, type-tested to 3250 VDC for 60 s.
- Fast hold-up time: 2 cycles at 50 or 60 Hz to bridge brief power dips.
- Chassis compatibility: Supports 1756-A4, A7, A10, A13, and A17 enclosures.
- Annunciator support: Rated for 240 VAC/240 VDC, 50 mA for external status indication.
The 1756-PAR2 delivers the reliability and precision required for redundant power architectures in critical ControlLogix applications.
