The 269PLUS-D/O-111-100P-HI is an Allen-Bradley (Rockwell Automation) MPR-Plus Motor Protection Relay with a specific configuration of digital outputs, communication, current rating, and other features. This advanced electronic relay provides comprehensive protection, control, and monitoring for electric motors in demanding industrial applications.

English Description

The Allen-Bradley 269PLUS-D/O-111-100P-HI is a highly configurable MPR-Plus Motor Protection Relay. It goes beyond basic overload protection, offering a wide array of protective functions, extensive diagnostic capabilities, and robust communication options for integrating motors into modern control systems.

Let's break down the specific configuration from the part number:

• 269PLUS: This indicates the MPR-Plus Motor Protection Relay product family, known for advanced motor protection and monitoring features.

• D/O: This segment specifies the Digital Output configuration. While the exact number of outputs isn't stated by just "D/O," it indicates a particular set of discrete output relays that can be programmed for trip, alarm, control, or status indication.

• 111: This code typically represents the Communication Protocol and/or other specific features. For the 269PLUS, "111" often signifies Modbus RTU communication as the primary serial communication interface. It might also encompass specific internal logic or I/O options.

• 100P: This denotes the Primary Current Rating of the relay. "100P" means the relay is designed to monitor a primary current of 100 Amperes (A), usually through internal current transformers (CTs) or by being directly rated for this current.

• HI: This suffix often refers to a High-Intensity, High-Accuracy, or specific Hardware/Firmware Revision. In the context of motor protection, it could imply enhanced accuracy for metering, extended diagnostic capabilities, or a specific hardware variant optimized for certain conditions or functionalities.

General features of the 269PLUS family (which this configured unit possesses):

• Comprehensive Protection: Includes thermal overload (Class 5-30 selectable), phase loss/imbalance, stall, undercurrent/overcurrent, jam, ground fault, under/over voltage, and power factor monitoring.

• Metering: Provides real-time motor operating parameters like current (A), voltage (V), power (kW), energy (kWh), power factor, and frequency.

• Diagnostics: Extensive diagnostic information, including trip history, event logs, and fault codes, aiding in troubleshooting and predictive maintenance.

• Control Power: While not explicitly in this string, 269PLUS relays typically support a range of control power voltages (e.g., 100-240V AC/DC or 24-48V AC/DC).

• User Interface: Features a local liquid crystal display (LCD) and keypad for programming and viewing status.

• Mounting: Flexible mounting options, including direct mounting to contactors or standalone DIN rail/panel mounting.

• Applications: Ideal for pumps, fans, compressors, conveyors, and other motor-driven equipment where critical protection, detailed monitoring, and integration into a supervisory control system are required.

This specific 269PLUS configuration is suited for applications involving 100A primary currents, utilizing Modbus RTU communication, and benefiting from advanced features for robust motor management.
