193-EIO-63-24D | Allen-BradleyE1 Plus Electronic Overload Relay

Product Overview

The Allen-Bradley 193-EIO-63-24D functions as a high-precision motor protection solution within the E1 Plus electronic overload relay family. This solid-state device monitors motor current with significantly higher accuracy than traditional bimetallic relays. We supply this unit as 100% Brand New original factory stock. It features a wide 5:1 adjustment range (12.6–63 Amperes) and utilizes a 24V DC control circuit, making it the ideal choice for modern automated control panels that prioritize energy efficiency and thermal sensitivity.

Technical Specifications

Engineering Advantages

• Solid-State Thermal Modeling: The 193-EIO-63-24D utilizes an internal microprocessor to simulate motor heating. This technology provides a "cool-down" memory, preventing motor damage from repeated "hot" starts that standard mechanical relays often fail to detect.

• Rapid Phase Loss Detection: The relay identifies a phase loss condition and triggers a trip in less than three seconds. This high-speed response protects motor windings from the catastrophic heat buildup associated with single-phasing, extending the lifecycle of expensive rotating equipment.

• Wide 5:1 Adjustment Ratio: A single 193-EIO-63-24D covers a broad current spectrum (12.6A to 63A). This versatility allows facilities to reduce spare parts inventory by using one relay model across multiple motor sizes and horsepower ratings.

• Low Energy Footprint: The electronic design consumes less than 150 mW of power. This minimal heat dissipation reduces the cooling requirements within the electrical cabinet, allowing for higher density mounting of motor starters.

• Visible Status Diagnostics: An integrated "Trip/Alarm" LED provides immediate visual confirmation of the relay status. Technicians identify the cause of a motor stoppage—whether a standard overload or a phase loss—without specialized diagnostic tools.

FAQs

• Can I mount the 193-EIO-63-24D separately from a contactor?

  Yes. While designed for direct mounting to Bulletin 100-C contactors, you can use a separate panel-mount adapter (such as the 193-EPB) to install the relay on a standard DIN rail.

• Does this relay require an external power supply for logic?

  The 193-EIO-63-24D is a self-powered device that draws energy directly from the motor leads for its sensing logic. The 24V DC specification refers to the control circuit compatibility for remote reset or signaling functions.

• Is the trip class adjustable on this model?

  The standard E1 Plus series features a fixed Class 10 trip characteristic. If your application requires Class 20 or 30 (for heavy-duty starting), you should consult the E200 or E300 series specifications.

• How can I be sure this is a 100% Brand New unit?

  We guarantee every 193-EIO-63-24D arrives in its Original Allen-Bradley Factory Box with intact security labels. Every unit features a clean, un-torqued set of terminal screws and a verifiable date code, ensuring you receive the full reliability of a new electronic component.
