Product Overview

The Woodward 5466-348 belongs to the Netcon family of serial I/O modules. This module interfaces with digital actuator drivers for precise position control. The Woodward 5466-348 has three independent RS-485 ports for flexible connectivity. You get one driver per port with a 5 millisecond update rate. Each port can operate at a different rate group. The Woodward 5466-348 detects communication faults and disables faulty drivers automatically.
