Woodward 8444-1092 Multifunction Relay / Measuring Transducer with CANopen / Modbus Communication

 

Functional Description

 

The 8444-1092 is a measuring transducer for monitoring single and three-phase power systems as a part of

MFR 300 series. The MFR 300 has both voltage and current inputs for measuring an electrical power source.

A digital processor makes it possible to accurately to measure true RMS values, regardless of harmonics,

transients or disturbing pulses. The primary measured and calculated values are transmitted via CANopen

/ Modbus protocol to a supervisory control system.

 

The MFR 300 performs monitoring functions for mains decoupling, including four freely configurable time-

dependent undervoltage monitoring functions for FRT (fault ridethrough).

 

The primary measured values of voltage and current are used to calculate the real, reactive, and apparent

power and the power factor (cosphi) values.

 

Features

 

• 3 true RMS voltage inputs

• 3 true RMS current inputs

• Class 0.5 accuracy for voltage, frequency and current

• Class 1 accuracy for real and reactive power or energy

• Configurable trip/control setpoints

• Configurable delay timers for individual alarms (0.02 to 300.00 s)

• 4 configurable relays (change-over)

• 1 "Ready for operation" relay

• Switchable relay logic

• 2 kWh counters (max. 1012 kWh)

• 2 kvarh counters (max. 1012 kvarh)

• CANopen / Modbus communication

• Configurable via CAN bus / RS-485 / Service Port (USB/RS-232)

• 24 Vdc power supply
