WOODWARD 5466-1158 MicroNet Simplex HDDIO High-Density Discrete I/O Module

Product Brief Description

Woodward 5466-1158 is a MicroNet Smart-Plus high-density discrete I/O (HDDIO) module for simplex control systems. It offers 48 discrete input channels and 24 discrete output channels for digital signal acquisition and relay drive. It plugs into the MicroNet chassis backplane and communicates with the main CPU for turbine auxiliary logic, status feedback and sequence control. This module requires matching FTM terminal boards, no potentiometer calibration needed, widely stocked as spare replacement for gas and steam turbine control cabinets.

Product Features & Functions
