PRODUCT INFORMATION
Product Overview
The Woodward 9906-619 is a low-voltage 723PLUS Digital Control hardware platform. This unit is a hardware-only build and contains no pre-loaded application software. It operates on an input supply range of 18 to 40 VDC. Nominal supply ratings are 24 VDC or 32 VDC with 40 watts power consumption.
The hardware is housed in a sheet metal chassis with three 9-pin D-sub connectors. Field connections wire into three onboard terminal strips. Two dedicated speed sensing channels accept magnetic pickups or proximity switches. Internal non-volatile EEPROM memory retains all configured operating parameters during power shutdowns.
