PLR Series Specifications
(Duplex Power Line Sensors)

TECHNOLOGY

The PLR sensors are designed for reliable real-time control and monitor applications. They comply with world-wide power line carrier transmission requirements.

The Duplex Power Line Sensor (PLR Series) utilizes advanced digital signal processing techniques, forward error correction and dynamic routing, resulting in highly reliable power line communications. All components are specified for extended industrial temperature and are typically encased in an epoxy-potting compound for use in harsh environments. The company's design and field experience in the area of power line surges, lightning transient protection, and electrical load interference have been applied to this product.

Features

Operates on all low voltage networks; supports 120 to 480 VAC, 50 and 60 Hz
Uses existing power line to communicate, does not require additional or dedicated wiring.
System is designed for outdoor, harsh environments; sensors are packaged in rugged, potted enclosures.
Provides an audit trail of luminaries and circuit operational status.
Able to keep detailed records of maintenance for each luminary, repair tracking.
Warranty tracking / asset management: Compare equipment life-span to manufactures' warranties.
Tracks maintenance personnel and contractor performance.
Master/Slave Topology
+ World-wide Compliant
+ Wide operating temperature range (-40 to + 80 C)
+ Effective data rate 2400 BPS
+ Single 5 amp triac output
+ Millions of nodes per logical network

Lighting Control Capabilities

Detects failed, cycling, and day burning lamps.
Detects faulty photocontrols.
Customers can access status and control information from any Internet accessible PC.
Track lamp life and trend lamp life cycles.
Tracks time-of-use and elapsed burn time.
Automatically sends status reports via E-mail on a user-configurable schedule.
Provides detailed and custom status reports; by specific areas, sites, clients, and time frame.
Fault Reports provide detailed information about failed lamps, including location description, replacement equipment part numbers, and special instructions.
Provides efficient work routes and enables predictive maintenance: Create an "area" failure and burn report to plan an efficient work route. Replace lamps near the end of their burn life at the same time.
Monitors branch circuit integrity
Meters Energy consumption for each service, circuit and load; presents detailed energy usage (15 minutes increments), and historic energy usage (daily / monthly / yearly).
Measures power quality parameters for each service, circuit, and load; parameters include RMS Voltage, RMS Current, Power, and Power Factor; presents most recent and historical data.
High/Low Watermarks - Time stamps each monitored points maximum voltage, current and power.
Ground Fault Detection - Monitors each branch circuit's leakage current.
Tripped Breaker - A circuit breaker is tripped open.
Branch Circuit Control - Energize/De-Energize branch circuits based on a configurable schedule.

Operation

The system operation is very simple. The Remote Sensor Modules (PLR) detects and measures the electrical properties of the device being monitored, such as a roadway light or electrical circuit.

When electricity is present, the PLR periodically transmits a short data message over the AC power lines. This message contains the detailed electrical status of its device, along with an identifying address unique to that PLR. This transmission is received and stored by a Data Logger installed on site.

The Data Logger contains a telephone or cellular data modem or other means of communications. On a scheduled basis or on demand, a computer will establish a connection with the Data Logger to update its configuration and collect status information.

The field status that is downloaded from the Data Logger is then processed and stored in a secured data base server. The database contains a cross reference of PLR addresses to user text fields enabling to display a detailed description of all monitored devices, their operational status, precise location, and related information.

This data is then accessible over the Internet for authorized users. A variety of custom status and trending reports are available that allow you to monitor and control your electrical and lighting systems.
