The GE DS200SHVMG1AED is a chassis-mounted hardware interface circuit board designed to safely bridge high-voltage silicon-controlled rectifier (SCR) M-Frame drive modules with secondary control architectures. It serves as a critical medium for interfacing the SCR bridge from M‑frame drives with power supplies found in DCFB or SDCI boards and the Power Connect Card (PCCA). The board provides a number of voltage and conversion functions, converting shunt signals ranging from –500 to 500 mV into differential frequency outputs from 0 to 500 kHz. Equipped with extensive galvanic insulation layers, multiple plug housings, and custom current attenuation parameters, this card protects delicate microprocessing boards by handling severe inline voltage feedback and ground loop cross-talk seamlessly.

² Functional Logic Bus Voltage: Tracks standard +5V DC, +15V DC, and -15V DC lines supplied

² Input Shunt Voltage Conversion Range: Receives raw low-voltage field signals between -500 mV and +500 mV

² Output Signal Frequency Density: Converts analog shunt signals to a precise 0 to 500 kHz

² Operating Temperature Limits: Engineered for industrial cabinet environments from 0°C to +60°C (+32°F to +140°F)

² Storage Environment Range: -40°C to +85°C (-40°F to +185°F)

² Operational Relative Humidity: 5% to 95% non-condensing moisture factor

(1) High-Voltage SCR Drive Interfacing: Serves as the critical power-conversion and communication medium bridging high-voltage SCR bridges with matching DCFB or SDCI control boards.

(2) Turbine Control Shunt Processing: Monitors isolated current loop signals directly from turbine generator field exciter components to track dynamic electrical shifts.

(3) System Isolation & Surge Safety: Acts as a vital safety filter layer inside industrial control panels to prevent high-voltage feedback transients from damaging central CPU logic modules.
