1756-PB75 Functional Description

The Allen-Bradley ControlLogix 1756-PB75 serves as a crucial DC-powered component within ControlLogix systems, specifically engineered to deliver stable backplane power for module operation. This power supply accepts a wide input voltage range of 18-32VDC with a nominal 24VDC, demonstrating excellent adaptability to industrial power variations. Its robust 75W output capacity ensures reliable performance across demanding operational environments.

This unit provides precisely regulated multiple voltage outputs, including 13A at 5.1VDC and 2.8A at 24VDC, catering to diverse module requirements within the chassis. The reinforced insulation design, tested at 3500VDC for 60 seconds, ensures exceptional electrical safety and system integrity. These technical characteristics make the ControlLogix DC 1756-PB75 Allen-Bradley particularly suitable for harsh industrial applications where power stability is critical.

Installation requires mounting in the leftmost chassis position, following specific wiring guidelines using 2.5 mm² copper conductors. The 1756-PB75 1756 Allen-Bradley ControlLogix Standard Power Supply 35-40ms power hold-up capability provides crucial buffer time during input power fluctuations, preventing unexpected system shutdowns. This feature significantly enhances overall system reliability in environments with unstable power conditions.

The POWER SUPPLY ROCKWELL 1756-PB75 maintains operational stability across a temperature range of 0-60°C and withstands substantial vibration levels. Its compact design combines durable construction with efficient heat dissipation, making AB 1756-PB75 POWER SUPPLY an optimal choice for continuous industrial automation applications where space constraints and thermal management are important considerations.
