Product Name Type Connectivity Product Description
Monitoring HardwareModbus, Modbus TCPThe BiTRONICS M871 Monitoring & Recording IED offers high-speed, high-accuracy power measurements for the electric utility substation. The M871 calculates True RMS Voltage, Current, and Watts every quarter cycle. Harmonics to the 63rd, K-Factor, Power, Frequency, sequence components, and many other measurements are updated every cycle. This calculation speed, coupled with a Modicon PLC on a Modbus or high-speed Modbus Plus LAN, enables control applications formerly unthinkable with measurement instruments. An optional 10/100 Mbps Ethernet port communicates with UCA2.0-Compliant protocols (OSI and TCP/IP simultaneously). The M871 is also a powerful recorder featuring waveform capture, accurate up to 100A ac symmetrical, with 128 samples per cycle resolution, two disturbance recording modes at rates of 1-3600 samples per cycle, sequence of event and trend recording. The combination of reliability and performance has made BiTRONICS brand meters the instrument of choice in substation applications.
