Woodward The controller’s dedicated TMR® Discrete I/O Module
This triple power supply structure provides maximum protection against single or multiple points of
hardware failure.
The controller’s dedicated TMR® Discrete I/O Module is designed for critical discrete circuits.
The module accepts discrete inputs and distributes them to each individual core section,
as well as outputs relay contacts to drive discrete application logic.
The module’s special TMR® outputs utilize a six-relay configuration and integrated potential fault
detection logic that allows any one or two relays to fail without affecting the integrity of the output
contacts.
This configuration allows routine relay testing and in-circuit repair without compromising output or
system integrity.
Designed from the ground up as a turbine control system, the MicroNet TMR® controller’s actuator
drive module is available with the use of single or dual redundant coils,
Proportional or integral turbine valve servos with AC or DC feedback position sensors using single or dual
redundant coils.
The MicroNet TMR® controller can accommodate any combination of Woodward MicroNet I/O modules
and LinkNet HT distributed I/O to provide maximum application flexibility.
