Description
Product Name: 193-ED1CB Allen Braley Output module
Product details:
The Allen-Bradley 193-ED1CB is an Electronic Overload Relay (EOCR) designed to provide reliable and accurate motor protection against conditions such as overload, phase loss, and phase imbalance. It is typically used in conjunction with a contactor to form a complete motor starter solution. The ‘193’ series is known for offering advanced protection features and higher precision compared to traditional thermal overload relays.
⚙️ Product Parameters (Specifications)

| Control Voltage | Typically 24V AC/DC or 110-240V AC (Varies by specific model code) |
| Trip Class | Selectable (e.g., Class 5, 10, 20, 30) to match application needs |
| Protection Functions | Overload, Phase Loss, Phase Imbalance/Asymmetry |
| Reset Method | Manual or Automatic (Selectable/Configurable) |

| Indicators | LED indicators for Run, Trip, and/or Fault conditions |
✨ Product Advantages
-
High Accuracy and Repeatability: Electronic sensing offers much greater precision in tripping characteristics than bimetallic thermal relays.
-
Selectable Trip Class: Allows the user to precisely set the tripping time (e.g., fast trip for critical loads or slower trip for high-inertia loads).
-
Phase Protection: Provides comprehensive protection against phase loss (single-phasing) and phase imbalance, which are common causes of motor damage. Traditional thermal relays are often less effective at detecting these issues quickly.
-
Wider Current Adjustment Range: A single electronic relay often covers a wider current range than a thermal relay, simplifying inventory.
-
Reduced Heat Sensitivity: Tripping is based on current measurement, making it less affected by ambient temperature changes in the control cabinet compared to thermal relays.
-
Space-Saving Design: Often designed for compact, direct mounting to contactors.
⚠️ Considerations (Important Notes)
-
Wiring Complexity: May require a separate control voltage supply and more complex wiring for the auxiliary contacts compared to simple thermal relays.
-
Calibration: The nominal current setting ($I_n$) must be set accurately, typically via potentiometers or digital settings, to match the motor’s full load current (FLC).
-
Compatibility: Ensure the specific 193-E model is physically and electrically compatible with the motor contactor it will be paired with (e.g., 100-C or 100-K contactors).
-
Environmental Factors: While less sensitive to ambient temperature, ensure it is installed within the specified temperature and humidity ranges.
🏭 Product Applications
The Allen-Bradley 193-ED1CB is ideal for any application requiring high-reliability and precise protection for three-phase AC motors, including:
-
Pumps and Fans: Protecting critical fluid handling and HVAC equipment.
-
Conveyors and Material Handling: Ensuring motors in production lines are reliably protected from jams or overloads.
-
Machine Tools: Used in machinery where precise motor control and protection are essential.
-
Compressors and Chillers: High-reliability protection for costly industrial refrigeration and air systems.
-
Any Motor Driven Load: Where the superior protection of phase loss/imbalance is required to extend motor life and minimize downtime.
