The 1756-CPR2 is a redundant power supply cable engineered by Allen‑Bradley for the ControlLogix platform. This 1756-CPR2 cable links a redundant power supply (e.g., 1756‑PA75R or 1756‑PB75R) to the 1756‑PSCA2 chassis adapter, enabling automatic failover in case of primary power loss. With a 0.91 m (3 ft) length and 14‑pin connectors, the 1756-CPR2 ensures seamless power distribution and synchronization between redundant supplies. The 1756-CPR2 is fully shielded to protect against EMI in demanding industrial environments.
Operating Temperature:0 °C to +60 °C (32 °F to 140 °F)
Storage Temperature:-40 °C to +85 °C
Minimum Bend Radius:12.7 cm (5.0 in.)
Minimum Clearance (left side) 12.7 cm (5.0 in.)
Shielding:Full shield with grounding braid for EMI/RFI suppression
Connector Protection:Gold‑plated contacts for corrosion resistance and low contact resistance
Redundancy Support: Enables automatic power failover between two redundant power supplies, minimizing system downtime
Plug‑and‑Play Design: Pre‑configured connectors eliminate wiring errors and simplify installation
Full Shielding: Shielded construction with grounding braid suppresses electromagnetic and radio‑frequency interference
Industrial Durability: Gold‑plated 14‑pin connectors resist corrosion and maintain signal integrity under repeated mating cycles
Precision Length: 0.91 m standard cable length is optimized for ControlLogix cabinet layouts
Active Lifecycle: Currently in production with ongoing factory support

Q1: What is the primary function of the 1756-CPR2?
A1: The 1756-CPR2 connects a redundant power supply to the 1756-PSCA2 chassis adapter, enabling automatic power failover for ControlLogix systems.
Q2: What is the length of the 1756-CPR2 cable?
A2: The cable is 0.91 meters (3 feet) long.
Q3: Which power supplies are compatible with the 1756-CPR2?
A3: It is compatible with 1756-PA72, 1756-PB72, 1756-PA75, and 1756-PB75 series redundant power supplies.
Q4: What is the bend radius of the 1756-CPR2?
A4: The minimum bend radius is 12.7 cm (5.0 inches), requiring at least 12.7 cm of clearance on the left side of the chassis.
Q5: Does the 1756-CPR2 support hot-swapping?
A5: No. Power must be removed or the area confirmed non‑hazardous before connecting or disconnecting the 1756-CPR2 to prevent electric arcing.
