Information About 1756-PA75R
The 1756-PA75R is a ControlLogix series redundant power supply engineered to operate outside the main chassis while supporting a paired module for uninterrupted system performance. It is compatible with multiple ControlLogix chassis sizes and integrates status indicators and solid-state relay outputs for monitoring system conditions. The module operates across a broad AC input voltage range and provides stable, temperature-rated output power for essential system components. It is designed to meet industrial EMC standards, ensuring reliable function in electrically noisy environments.
Key Features:
- Redundant Power Architecture: Enables pairing of two modules for automatic load sharing and continuous system availability.
- Wide Input Voltage Range: Accepts 85–265 VAC at 47–63 Hz for flexible installation worldwide.
- Stable Output Power: Supplies 75 W across multiple regulated backplane voltage rails for ControlLogix modules.
- Compatibility with ControlLogix Chassis: Supports chassis models from 1756-A4 through 1756-A17.
- Integrated Status Indication: Includes LED indicators and solid-state relay signaling for supply and system state monitoring.
- Robust EMC Protection: Tested to IEC 61000-4-5 and CISPR 11 standards for surge and RF immunity.
- High Inrush Current Handling: Supports up to 20 A inrush current to accommodate demanding startup conditions.
- Panel-Mounted Installation: Designed for secure external mounting using approved redundant power supply accessories.
The 1756-PA75R delivers the reliability and precision required for continuous-duty industrial control and automation power distribution.
