2080-PS120-240VAC | Allen-Bradley | Micro 800 Programmable Logic Controller

Product Overview

The 2080-PS120-240VAC is a high-efficiency external power supply module specifically engineered for the Allen-Bradley Micro800 programmable logic controller family. It functions as a reliable power source for Micro810, Micro820, Micro830, and Micro850 controllers, converting standard AC line voltage into the regulated 24V DC required for CPU and I/O operation. This module is essential for applications where the integrated controller power is insufficient or where a dedicated, isolated power source is preferred to enhance system stability.

Application Scenarios

The 2080-PS120-240VAC is typically utilized in compact control panels where space is at a premium. It is the standard choice for powering Micro850 controllers and expanded 2085 I/O banks in material handling systems, packaging machinery, and localized HVAC control units. Its high inrush current tolerance makes it suitable for environments with heavy inductive loads on the same power line.

Frequently Asked Questions

Q: Can this power supply be used to power field devices like sensors and actuators?A: While its primary role is powering the Micro800 controller and plug-in modules, it can supply 24V DC to field devices provided the total current draw does not exceed the 1.6A limit.

Q: Does the 2080-PS120-240VAC support redundant configurations?A: No, this is a standalone power supply. If redundancy is required, external diode-logic or specialized redundancy modules must be integrated into the circuit.
