Key Benefits

The 469 Motor Management Relay is intended for protection and management of medium and large horsepower motors and driven equipment. Motor protection, fault diagnostics, power metering, and communications functions have been integrated into one complete, economical, drawout package.

New in SR469:

• Embedded DeviceNet Protocol allows the 469 to communicate to remote control centers via DeviceNet based networks, quite popular in industrial applications, particularly in factory automation.
• Embedded Ethernet communication allows the 469 to be connected directly to Ethernet Local/Wide Area Networks (LAN/WAN) supporting baud rates of up to 10Mbps, using Modbus TCP/IP protocol, via an RJ45 port located on the back panel of the relay.
• In addition to the benefits introduced with embedded Ethernet and DeviceNet communications, take advantage of the following new additional features included with the product:
• Expanded sequence of event recorder - 256 time stamped events
• Expanded Waveform capture – up to 128 cycles

• Unique protection features | Comprehensive motor protection plus voltage dependant overload curves, torque metering and protection, broken rotor bar protection
• Most advanced thermal model | Including multiple RTD inputs for stator thermal protection
• Advanced monitoring functions | vibration, bearing temperature
• Best in class man machine interface (MMI) | Large backlit display with 40 characters to view relay information and settings in direct sunlight, full numerical keypad, and setpoint navigation keys.
• Minimize replacement time | Draw-out construction
• Complete asset monitoring | Temperature, Analog I/O, full metering including demand & energy
• Improve uptime of auxiliary equipment | Through I/O monitoring
• Reduce troubleshooting time and maintenance costs | Event reports, waveform capture, data logger
• Simplify testing | Built in simulation features
• Cost effective Access to information | Via Modbus RTU protocol, through standard RS232 & RS485 serial ports, and optional Modbus RTU over TCP/IP through embedded Ethernet Port to connect to 10MB Ethernet local or wide area networks.
• Follow technology evolution | Flash memory for product field upgrade
• Long lasting life when exposed to chemically corrosive and humid environments with optional conformal coating
