General Electric WESDAC D20A

Brief Description

WESDAC D20A is a GE Multilin 32-channel DC analog input module for D20 substation RTU and automation system. It pairs with WESTERM D20A termination board to collect analog transducer signals and transmit conditioned data to the D20 main CPU for SCADA monitoring.

Product Features & Functions

• 32 differential analog input channels for voltage and current loop signals
• Programmable input ranges: ±1V, ±5V, ±10V for flexible field matching
• Integrated A/D conversion with excellent noise rejection for 50/60Hz power systems
• Surge protection and isolation for substation harsh EMI environments
• D20 Link communication interface to exchange data with D20 controller
• Supports wetting voltage supply for 4-20mA field transmitters
• Configurable scan rate and per-point deadband to reduce unnecessary data updates

Application Scenarios

• Electrical substation D20 RTU and substation automation systems
• Power plant SCADA data acquisition cabinets
• Transmission and distribution feeder monitoring panels
• Transformer, generator and meter analog signal collection
• Legacy GE D20 system maintenance and spare replacement
