Allen‑Bradley 1769-PA4 Product Introduction

Allen‑Bradley 1769-PA4 is a product of the Allen-Bradley brand of Rockwell Automation.As part of the CompactLogix series,it is designed for medium to large automation control systems.

Functional Features

Power supply:This module can provide 120 to 240 volts AC power and 24 volts DC power for CompactLogix 1769-L3x processors,controllers,and I/O modules connected to them.

Module connection:Up to 8 modules can be connected to each side of 1769-PA4,and up to 16 modules can be connected to one power supply.At 5 volts DC,it can provide 2 amps of current(4 amps in total),or 1 amp of current at 24 volts to each module on both sides of the power supply(2 amps in total).

Installation and applicability:The power module measures 2.76 x 3.43 x 4.65 inches,weighs about 500 grams,and can be mounted on a DIN rail or panel.It is suitable for open housings and does not require an additional housing.

Components and safety:The 1769-PA4 includes components such as a bus joystick with locking function,an LED status indicator,and a power door with an identification label.To ensure safety,users can only use Littelfuse 02183.15MXP or Wickman 19195-3 fuses.
