5501-467 Analog Input/Output Module Woodward

This model is an important component of the Woodward MicroNet series control system and is typically used as a high-performance analog input/output module or signal conditioning board.

1. Product Description

The Woodward 5501-467 is a universal analog I/O module specifically designed for the MicroNet digital control system.

The MicroNet system is a highly representative and reliable control platform in the industrial field.

The 5501-467 module is responsible for connecting various sensors (such as pressure, temperature, and flow transmitters) and actuators (such as proportional fuel valves) at the site.

It has high-resolution data acquisition capabilities, which can convert the analog current or voltage signals from the site into digital signals that the controller can handle, and can output precise control instructions.

2. Technical Data Sheet
