Woodward 5466-1000 Module Description

The LINKnet 6Ch RTD Module interfaces to six temperature sensing three-wire RTD transducers.

The module comes in two different RTD resistance ranges (100 and 200 ?).

Both types of modules have unique part numbers and interface to one of the four channels on the 4Ch LINKnet Controller Module through a serial network cable.

See Appendix A for the desired part numbers.

The module has a built-in reference voltage that is used to verify the proper operation of the A/D converter.

Appropriate faults are annunciated through the application program.

Up to 60 nodes or LINKnet, I/O modules can be connected to each channel of the LINKnet Controller Module.

Dual Solenoid Monitor Module

This module is used to monitor and control two independent solenoid current inputs for low or high current failed trips.

The module uses discrete and analog components, to minimize the time to detect and output signals, when an event occurs.

This module is used primarily for GE LM (Land & Marine) gas turbines and is usually used in conjunction with a Dual Overspeed Module.

The Dual Solenoid Monitor module is used to directly interface with the gas turbine fuel inlet solenoid valves.

This module requires external solenoid driver components to interface to the fuel valve solenoid.

The drivers are mounted externally from the module for heat dissipation purposes.

The components for each channel are completely independent of each other so that a chip or component failure will only affect one channel and not both.

The module has test features to allow each channel to be tested.

This module will plug directly into any slot of a MicroNet rack, but it has no interface to the data or address busses of the MicroNet.

The only interface to the MicroNet backplane is for power supply inputs.

The module has 2 potentiometers for factory adjustments.

The potentiometers are for adjusting the undercurrent trip points for the solenoid currents

The module I/O has been designed to minimize the interconnection to external power sources and/or circuit commons.

All of the input signals are set by allowing the input to float (pulled high to +5 VDC) or by connection to the module circuit common through a dry relay contact (pulled low to circuit common).

The module has two types of output signals that provide an interface to MicroNet discrete input modules or interposing relay coils (indication outputs).

Woodward 5466-1000 Description of MicroNet Plus

Woodward input that is used to power the solenoid

drive circuits as well as the over and under current

circuits. This source is usually supplied by the

customer and is tapped off of the power supply for

solenoids. This input supply is isolated from all of the

MicroNet power supplies through optoisolators.

NOTE: Use both pins to distribute current demand.
