Functional Description

5461-775 is a Ambient bias ramp module developed by Woodward. The module's primary function is to regulate the ambient bias ramp, which refers to the gradual adjustment of operating conditions to accommodate changes in the surrounding environment. It leverages sensor technology and sophisticated algorithms to continuously monitor ambient conditions such as temperature, humidity, pressure, and other relevant parameters. This real-time data is then processed and used to modulate the system's performance, allowing it to adapt seamlessly to environmental changes.

Product Attributes

• Designed to control the ambient temperature within a gas turbine, allowing for precise control of the turbine's operation.
• Ramp function for controlling the rate of change of the ambient temperature, allowing for gradual temperature changes and preventing thermal shock to the turbine components.
• Compatible with various types of temperature sensors such as thermocouples, RTDs, and thermistors.
• User-friendly interface that allows for easy configuration and monitoring of the ambient temperature control process.
• Communicate with other devices and systems using various communication protocols, allowing for integration with control systems.

MicroNet TMR Control System

• The MicroNet TMR control platform achieves 99.9% availability by utilizing a robust rack-mounted chassis with on-line replaceable I/O modules and a triple modular architecture. This triple modular redundant system is made up of three isolated kernel sections (A, B, and C) that are housed within the platform's compact chassis. Each kernel section has its own CPU, power supply, and up to four I/O modules. The I/O modules can be used for simplex I/O, redundant I/O, triple redundant I/O, or any redundancy combination. I/O can be expanded using system expansion chassis or rugged LinkNet HT distributed I/O. This platform's high-density modules and integrated application program provide first-out indication for monitored system events, reducing troubleshooting time.
• These custom-built modules time stamp discrete events in one millisecond and analog events in five. The MicroNet TMR is powered by two separate power supplies, each of which powers the control. There are three independent power converters inside each power supply, one for each CPU and I/O section. This triplicate power architecture offers the best protection against single and multi-point hardware failures. TMR Discrete I/O modules are specially designed for use in critical discrete circuits. This module accepts discrete inputs and distributes them to the various kernel sections, as well as outputting relay-based contacts to drive discrete application logic.
• The special TMR outputs of the module use a six-relay configuration and integrated latent fault detection logic to allow the failure of any one or, in some cases, two relays without affecting the output contact's integrity. This architecture enables routine relay testing as well as on-line reparability without compromising the output or system's integrity.

Frequently Asked Questions

What is 5461-775?
It is Ambient bias ramp module developed by Woodward.

Can the TMR controller operate with a failed CPU module?
Yes, the controller's architecture allows it to function normally even if a CPU module fails or is removed. The fault-tolerant logic ensures continuous operation and safe shutdown in the case of multiple CPU failures.

How does the TMR controller handle failures in analog I/O modules?
The controller is designed to maintain functionality even if one or two analog I/O modules fail or are removed. It employs fault-tolerant logic to ensure normal operation and seamless handling of analog signals.

What is the fault tolerance logic for power supply failures in the system controller?
The controller incorporates a power supply fault tolerance logic of 2-1-0. This means it can continue operating normally even if one power supply fails or is removed, ensuring uninterrupted functionality and system stability.
