Product Details
Product Overview
The Allen-Bradley 1783-MMX16T provides essential fault-tolerant capabilities for critical 24-28V DC power systems. This Bulletin 1606 redundancy module decouples two power supplies, preventing a single failed unit from pulling down the entire DC control bus. We supply this module as 100% Brand New and Original, ensuring your automated systems maintain continuous uptime even during power supply failures or maintenance intervals. It supports a massive 1920 Watts of throughput, making it the standard for high-current industrial applications.

Engineering Advantages
-
Lossless Decoupling Logic: The 1606-XLSRED80 utilizes high-performance diode or MOSFET technology to isolate parallel power supplies. This isolation prevents a short circuit on the input side of one power supply from affecting the output bus, ensuring the secondary supply takes over the load instantly.
-
Massive Current Handling: This module manages up to 80 Amps in dual-input mode. It accommodates large-scale I/O racks and high-power motor drives within a compact 1.00 lb housing, eliminating the need for bulky, custom-built diode arrays.
-
Streamlined Troubleshooting: The module simplifies diagnostic routines by providing clear separation between power sources. Maintenance teams can hot-swap a failed power supply unit without shutting down the controller or the manufacturing line.
-
Passive Cooling Efficiency: The hardware design maximizes heat dissipation without internal fans. This enhances reliability in dusty or oil-mist environments common in automotive and heavy machining industries, where fan-based cooling often leads to premature component failure.
FAQs
-
What is the voltage drop across this module?
The 1606-XLSRED80 incurs a nominal voltage drop of approximately 0.7V DC between the input and output. To maintain exactly 24V DC at your load, adjust the output voltage of your primary power supplies to 24.7V DC.
-
Can I use this module to combine two different power supply brands?
Yes, provided both power supplies operate within the 24-28V DC range and share a common ground. However, for optimal load balancing and thermal stability, we recommend using matched Allen-Bradley 1606 series power supplies.
-
Does this unit ship in original factory packaging?
Absolutely. We ship each 1606-XLSRED80 as 100% Brand New original hardware in its factory-sealed box. This guarantees the integrity of the internal components and ensures the product meets all original manufacturer performance specifications.
-
How do I wire this for maximum redundancy?
Connect the output of "Power Supply A" to Input 1 and "Power Supply B" to Input 2. Join the common output terminal to your load. This configuration allows the 1606-XLSRED80 to pull the full 80A current capacity or provide a 1+1 redundant failover for 40A loads.

Navigating Industrial Automation Failures: Types, Causes, and Mitigation Strategies
Modern manufacturing relies heavily on automated control systems to maximize throughput and maintain product quality. However, unplanned downtime in industrial automation can cost facility operators thousands of dollars per hour. Understanding how programmable logic controllers (PLCs), distributed control systems (DCS), and field instrumentation fail empowers engineering teams to implement robust preventive maintenance strategies.
Essential Motion Control Commands: A Practical Guide for Engineers
Automation engineers often rely on precise position and speed control to drive modern factory machinery. Modern industrial systems, such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS), depend heavily on standardized motion instructions. Mastering these commands ensures operational safety, protects mechanical components, and optimizes cycle times across production lines.
The Role of Intrinsic Safety Barriers in PLC and DCS Architectures
Implementing robust protection in hazardous industrial environments represents a fundamental safety requirement in factory automation. Process facilities often handle volatile gases, dusts, and chemical agents that pose significant combustion risks. Consequently, control system engineers must deploy energy-limiting interfaces to isolate safe-area control cabinets from hazardous-area field instrumentation. This article examines the function, selection, and electrical principles of intrinsic safety barriers within modern PLC and DCS networks.
