1738-EP24DC | Allen Bradley | ArmorPoint I/O Expansion Power Module

Product Overview

The Allen Bradley 1738-EP24DC serves as a critical on-machine power expansion component for the ArmorPoint I/O system. This module extends the backplane power (PointBus) capacity, allowing for larger distributed I/O configurations without returning to the main control cabinet. It features a fully sealed, ruggedized housing designed for direct mounting on machinery in the harshest industrial environments. We supply this unit as 100% Brand New original factory equipment, ensuring maximum uptime and ingress protection for your decentralized control architecture.

Technical Specifications

Engineering Advantages

• Extreme Ingress Protection (IP69K): The 1738-EP24DC features a fully encapsulated design that meets IP69K standards. This rating ensures the module withstands high-pressure, high-temperature washdowns (up to 1450 psi and 80°C), making it ideal for food processing, beverage, and pharmaceutical applications where sanitation is mandatory.

• Decentralized Power Boost: This module solves the common issue of voltage drop in long distributed I/O strings. By injecting an additional 1.3A of 5V DC power directly into the PointBus, it supports the addition of more I/O modules further away from the primary adapter, eliminating the need for bulky secondary enclosures.

• Cabinet-Free Installation: The rugged ArmorPoint hardware removes the requirement for a protective NEMA or IP-rated electrical cabinet. You bolt the module directly to the machine frame, which significantly reduces installation costs, saves floor space, and simplifies field wiring using quick-disconnect M12 connectors.

• High Vibration Resistance: Engineered for "on-motor" or high-vibration tool-mounting applications, the 1738-EP24DC maintains electrical contact integrity where standard DIN-rail mounted PLCs would fail. This ensures continuous power delivery to sensors and actuators in high-impact environments.

FAQs

• When exactly do I need to add a 1738-EP24DC to my ArmorPoint assembly?

  You must install this expansion power module when the total current draw of the I/O modules on the PointBus exceeds the current supplied by the primary communication adapter. Use it to "break" the bus and provide fresh 5V DC power to the subsequent modules in the chain.

• Can the 1738-EP24DC withstand chemical cleaning agents?

  Yes. The outer housing materials specifically resist common industrial detergents and chemical sanitizers used during washdown procedures in hygienic zones. Always ensure all unused M12 ports have proper sealing caps to maintain the IP69K rating.

• Is this a refurbished or surplus unit?

  No. We guarantee this 1738-EP24DC is 100% Brand New original stock. It ships in the original Allen Bradley factory packaging, complete with the manufacturer’s seal, ensuring you receive the latest hardware revision with full factory specifications.

• Does this module require a separate ground wire?

  The module establishes a ground connection through the mounting hardware to the machine frame. For optimal noise immunity and safety, ensure the mounting surface is clean and provides a low-impedance path to the system ground.
