WOODWARD 8444-1092 MFR300-75M

8444-1092 Performance Features：
High-precision measurement: Equipped with 3 true RMS voltage inputs and 3 true RMS current inputs, it can accurately measure basic electrical parameters such as voltage, current, and frequency. The voltage, frequency, and current measurement accuracy can reach 0.5 level, and the active power and reactive power or energy measurement accuracy can reach 1 level.
Comprehensive calculation function: It can calculate parameters such as actual power, reactive power, apparent power, and power factor based on the measured voltage and current values, and provide calculation and monitoring of multiple derived values ​​such as average voltage and average current, providing rich data support for system operation analysis and energy efficiency evaluation.
Flexible protection function: It has multiple protection functions such as overvoltage, undervoltage, overfrequency, underfrequency, voltage asymmetry, overload, positive/negative load, unbalanced load, phase shift, overcurrent, etc., which can effectively prevent electrical equipment from being damaged due to abnormal working conditions and ensure the safe and stable operation of the system. .
Configurable alarm and control: Users can flexibly configure alarm thresholds and control logic according to specific needs to achieve accurate monitoring and automatic control of electrical systems, such as setting different voltage and current alarm values, and configuring the action conditions and logical relationships of relays.
Powerful communication capabilities: Supports CANopen and Modbus communication protocols, and can be configured and data transmitted through CAN bus, RS-485 or service port (USB/RS-232), convenient for integration with host computers, PLCs, DCS and other monitoring systems, to achieve remote monitoring and centralized management.

8444-1092 technical parameters：
Input parameters: The voltage input range is generally 0-500V AC, and the current input range is generally 0-5A AC. Suitable transformers can be selected for signal conversion according to actual applications.
Output parameters: It has 4 configurable conversion relays and 1 "ready to run" relay. The relay output contact capacity is generally 5A/250V AC or 5A/30V DC, which can be used to control external devices or send alarm signals.
Power requirements: 24V DC power supply, the power supply voltage range is generally 18V DC-32V DC, ensuring stable operation in industrial environments.
Working environment: The working temperature range is generally - 20℃-+60℃, and the relative humidity range is generally 5%-95%, without condensation, which can adapt to relatively harsh industrial field environments.
