Overview
The Allen-Bradley 1400-PD52A power monitor display module is a dedicated electrical measurement instrument designed for substations, distribution centers, and industrial motor control centers. This discontinued unit consolidates monitoring of up to 12 electrical variables on a single integrated display, replacing the need for multiple analog instruments traditionally used in power distribution applications.
Key Features
- Monitors line-to-neutral and line-to-line voltages across three phases
- Measures phase current plus a fourth current input for auxiliary circuits
- Tracks frequency, power factor, kVA, kW, kVAR, and kW/kVA demand
- Auxiliary voltage input (VAUX) monitoring capability
- Integrated safety relays with over/under voltage and unbalance protection
- RS-232 and RS-485 serial communication ports for remote SCADA integration
- Allen-Bradley Remote I/O communication support
- IP 54 protection rating for industrial environments
- Data logging and remote control capabilities
Technical Specifications
- Operating Voltage: 277–480 V AC, three-phase
- Current Rating: 5 A
- Communication Ports: RS-232, RS-485, Allen-Bradley Remote I/O
- Protection Rating: IP 54
- Weight: 7.01 lbs
- Status: Discontinued by manufacturer
Typical Applications
- Electrical substations and distribution centers
- Industrial motor control centers (MCC)
- Power plant metering and monitoring
- Manufacturing facility power distribution
- Energy auditing and power quality assessment
Compatibility & Replacements
The 1400-PD52A is discontinued by Allen-Bradley. For new installations requiring multi-parameter power monitoring, contact a Rockwell Automation distributor for current alternatives in the PowerMonitor or industrial HMI product lines. Used units remain available through surplus distributors such as Radwell, IMS Supply, and DO Supply, often with refurbished or remanufactured warranty options.
