Description
The GE Fanuc WESDAC D20 C is a Status Input Module designed for GE Digital Energy WESDAC D20/D200 Remote Terminal Unit (RTU) systems. It provides digital status acquisition and communication functions for substation automation, SCADA systems, and electrical power monitoring applications.
The D20 Status Input Module is designed to collect field status signals and transmit processed information to the main D20 processor through the D.20 communication link. It is widely used in utility automation systems for monitoring breakers, switches, alarms, and other discrete field devices.
The module architecture consists of the WESDAC logic module and WESTERM termination interface, allowing field wiring connection, signal processing, diagnostics, and simplified maintenance replacement. The system supports up to 64 digital status inputs depending on configuration.
