Description

The Allen-Bradley MOX12/4U-P3509B (Order Code: 80026-173-23) is a high-reliability DC/DC power supply module designed for demanding industrial automation and safety-critical environments. Housed in a robust metal enclosure, this unit provides stable, regulated power output to sensitive control electronics. It is engineered to maintain performance in harsh conditions, featuring conformal coating on internal circuit boards to resist moisture, dust, and atmospheric contaminants.

Features

• Robust metal enclosure for enhanced durability and EMI shielding
• Conformal coated circuit boards for environmental protection
• High efficiency operation (up to 90%) to minimize thermal dissipation
• Integrated LED status indicators for local diagnostics
• Built-in protection against overcurrent, overload, and short-circuit conditions
• Chassis-mount design for secure installation in control cabinets

Applications

• Safety Instrumented Systems (SIS) and critical control loops
• Oil & Gas pipeline pumping stations and gas compression control
• Power generation facilities (ID/FD fan control systems)
• Municipal water and wastewater treatment pump control
• Petrochemical processing equipment including mixers and extruders

Technical Specifications

Installation Guidelines

• Ensure the power supply is disconnected from the AC source before performing any wiring or installation.
• Mount the module in a well-ventilated area to allow for natural convection cooling; maintain adequate clearance around the enclosure.
• Use appropriate wire gauges for input and output connections to prevent voltage drop and overheating.
• Ensure a solid chassis ground connection to the metal enclosure to maintain EMI/EMC compliance.
• Verify that the input voltage matches the module's rated range (100-240V AC) before energizing.
• Handle with care to avoid damage to the conformal coating; observe standard ESD precautions when handling the module.

FAQs

What is the primary application of the 80026-173-23?
