The Advanced Featuresinclude a Color Touchscreen Operator InterfacePanel that provides simple programmingwith no keyboards or cryptic labels. The paneldisplays loop status, alarm conditions andgraphics on currents.With the built-in power distribution, the Intelli-TRACE multi-loop provides reduced material,installation, and maintenance costs. Theload management feature eliminates the needfor expensive ground fault breakers, limitsinrush current and systematically interrogatesall circuits for continuity and ground faultleakage.Technical SpecificationsSupply Voltage: 120, 240, 480, and 277Vac,Three-PhaseOperating Environment: 32 to 120°F(0 to 40°C) -30 to 104˚F (-34 to 40˚C) withenclosure heater optionCommunications: RS-485 MODBUS ®Output: Two-Pole ContactorsMaximum Current: 24 Amps/CktGround Fault Alarm: Adjustable 25 – 500mAFactory Set @ 30mALow Current Alarm: .2 - 24.0 AdjustableLoad Management: 15 sec.
