Woodward 9907-147 ProTech Control Module

Description

The Woodward 9907-147 is designed to monitor prime mover speed for overspeed conditions using magnetic pickups. It is susceptible to electromagnetic interference, vibration, moisture, and temperatures outside of the operating temperature range of –25 to +60 °C (–13 to +140 °F). The device should be installed in locations that allow adequate ventilation for cooling, space for servicing, and away from direct sunlight and high-current or high-voltage devices.

Features

• 24Vdc Input: Ensures reliable power supply.
• CPU and MPU Failure Indication: Provides alerts for any failures in the CPU or MPU.
• Lockable Enclosure: Prevents unauthorized access.
