Features:

  • Supports 24 V DC auxiliary power input with stable operation in industrial control systems.
  • Accepts 5 A AC measurement input and supports standard industrial voltage levels up to 150 V AC.
  • Designed for reliable performance in -20°C to 70°C operating environments for power and automation applications.
Woodward, Inc. 8444-1002 Measuring Transducer is widely used in industrial power monitoring systems where accurate electrical signal conversion is required. It plays an important role in collecting and processing voltage and current signals for control and protection functions. The device is commonly integrated into turbine control and energy management systems. Its design supports stable measurement performance in continuous industrial operation environments.

In practical applications, Woodward, Inc. 8444-1002 helps ensure that electrical parameters such as current and voltage are accurately transferred to control units. This improves system visibility and supports reliable decision-making in automation processes. The device operates under standard industrial frequencies of 50/60 Hz, making it compatible with most global power systems. Its stable auxiliary power design ensures consistent performance in control cabinets.

From an engineering perspective, Woodward, Inc. 8444-1002 is designed for durability and measurement stability across different operating conditions. It can function in environments ranging from -20°C to 70°C, making it suitable for both indoor and semi-industrial installations. Compared with communication-oriented modules like MFR-300 (8444-1090), this model focuses more on direct signal measurement rather than fieldbus integration. This positions it as a reliable solution for traditional industrial measurement architectures.

The 8444-1002 Woodward Measuring Transducer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Woodward 8444-1002 Measuring Transducer is designed for industrial signal measurement and conversion in power control and automation systems. It operates as an interface device that processes electrical parameters such as voltage and current, ensuring accurate transmission of measurement data to control systems. The unit is widely used in energy management and turbine control applications where stable signal handling is required.

The device supports a nominal frequency of 50/60 Hz and is designed to operate with an auxiliary supply of 24 V DC (U oux). It accepts an input current of 5 A AC (I 1/G) and provides an auxiliary output current of up to 0.5 A DC (I oux.,max), making it suitable for integration into industrial measurement loops. The rated AC voltage levels include 57/100 (120) V AC according to IEC standards and up to 150 V AC under UL conditions.

Woodward 8444-1002 Measuring Transducer is engineered for reliable operation across industrial environments, with an operating temperature range from -20°C to 70°C. This allows stable performance in both indoor control cabinets and field-installed power systems. The device ensures consistent measurement accuracy under varying electrical and environmental conditions.

Compared with the related configuration option MFR-300 (8444-1090), which can be used for CANOpen or ModBus RTU signal applications, the Woodward 8444-1002 focuses on direct electrical measurement and signal transduction rather than fieldbus communication integration. This makes 8444-1002 more suitable for traditional measurement-based monitoring architectures, while MFR-300 provides broader communication protocol flexibility in modern networked systems.
