Continental Control Systems, LLC


Type:  Monitoring Hardware
Description:  The WATTNODEŽ MODBUS is a kW hour/kWh energy meter that communicates on an EIA RS-485 network measuring 1, 2, or 3 phases or loads with voltages from 120 to 600 volts AC and 5 to 6000Amps in Delta (phase to phase) and Wye (phase to neutral) configurations. The Modbus interface networks AC power measurement, true RMS power and energy, energy and demand metering, kWh reactive power, VARs, power factor, line frequency providing both individual and combined phase measurements.
Connectivity:  Modbus RTU
Features:  Low profile - compact dimensions; pluggable screw terminals; line powered; .5% nominal accuracy; uses low voltage CTs; CE Certified; UL and cUL Listed; measures 1, 2, or 3 phases, allows up to 127 WATTNODES per RS-485 subnet; low cost; measurement of true RMS power; reactive power; power factor; true RMS energy; reactive energy; AC frequency; RMS Voltage; RMS current; demand; peak demand.
Specifications:  Modbus RTU; EIA RS-485 interface; baud rates; 9600 and 19,200; response time: 5-300 milliseconds; operating Voltage 0 -.5 VAC; power line frequency - 50-60Hz; 1,2,or 3 phase; Delta and Wye configurations.
