WOODWARD 8402-319/8402-119 Actuator Control Modules
1. Product Description
The WOODWARD 8402-319 and 8402-119 are advanced single- and dual-channel actuator control modules designed for precise positioning in industrial automation systems. These modules are widely used in power generation, oil & gas, and process control applications, ensuring reliable operation under harsh conditions. The 8402-319 supports dual-channel redundancy (200 mA per channel), while the 8402-119 offers a single-channel configuration. Both models feature PWM-based output, LVDT/RVDT feedback compatibility, and real-time diagnostics for optimal performance and safety.
