A-B 1756-PA75 is a product launched by Rockwell Automation.The following is a detailed introduction to the product:
1.Product Overview
A-B 1756-PA75 is a ControlLogix power module,belonging to the Allen-Bradley series.It is a standard power supply designed for the ControlLogix chassis.It is installed on the dedicated power slot on the far left of the chassis to provide the necessary backplane power for each module installed in the chassis so that they can enter the operating state.
2.Technical Specifications
Input voltage:This power module can accept a wide range of external power supply voltages,usually 85265VAC and a frequency of 4763Hz.This allows it to adapt to power supply standards in different countries and regions,facilitating global applications.The nominal input voltage is 120VAC/240VAC.
Output capacity:The rated output power is 75W(within the temperature range of 0~+60°C).At the same time,it also provides a variety of voltage and current output options to meet the needs of different devices.Specifically,the current capacity is 3A at 4.3VDC;1A at 13.5VDC;and 8.24A at 2V DC.
Compatibility:This power module has good compatibility with other products and systems of Rockwell Automation.It is suitable for various ControlLogix chassis,such as 1756-A4,1756-A7,1756-A10,1756-A13,1756-A17,etc.,especially the B series and C series.
