Functional Description

5466-045 is a Pressure Xducer Interface Module developed by Woodward. The Interface Module is a specialized input module designed to interface with external pressure transducers in control systems. This module plays a key role in gathering pressure data and ensuring that it is properly communicated to the main CPU module for further processing and control actions.

Features

• Each port can handle multiple pressure transducers, allowing for up to eight pressure transducers to be connected to a single interface module. This capability makes it highly versatile, as it can gather pressure data from multiple sources and consolidate them for processing, ideal for complex control systems that need to monitor several points of pressure.
• The pressure data collected from external transducers is transferred to the main control system via the dual-port RAM on the VME bus. This ensures high-speed, low-latency data communication between the interface module and the main CPU module, enabling quick response times and real-time monitoring.
• The module is built with electrical isolation features to protect sensitive equipment and reduce the risk of damage due to power surges or ground loops. This feature ensures that pressure data remains accurate and that the control system’s components are shielded from potential electrical faults, particularly in harsh industrial environments.

Simple and Secure Module Installation

• It slides into card guides and plugs directly into the motherboard, ensuring secure connections.
• The module is held in place by two screws at the top and bottom of the unit, providing stability during operation.
• Handles at the top and bottom allow for easy removal of the module when necessary. By toggling the handles, the module is disengaged from the motherboard connectors, facilitating quick maintenance and replacement.

Dual Isolated RS-422 Communication Ports

The module features two isolated RS-422 communication ports, which are used to connect to external pressure transducers. These communication ports are designed to handle pressure measurement data efficiently and accurately:

• Each RS-422 communication port consists of a pair of differential transmit lines, a pair of differential receive lines, and +15 V power connections.
• The module ensures that both communication ports are electrically isolated from one another and the rest of the module, protecting sensitive data and equipment from electrical interference and noise, especially in high-voltage environments.
