Product Overview
6DD1606-2AC0 is a SIMADYN D PT20G processor module for technological open- and closed-loop control, arithmetic and drive-related functions. It combines a PT20 basic board with a TG1 submodule.
The module supports line-commutated SITOR converters through its dedicated interface, while analog, binary, speed sensing and serial connections serve the installed control application.
Key Functions
Real-time control
The 80C186 processor runs the SIMADYN D operating system and processes configured technological and drive control tasks.
Integrated signal processing
Seven analog inputs, four analog outputs, 24 binary inputs, 16 binary outputs and two speed sensing inputs connect to field signals.
Converter control and diagnostics
The X8 interface provides SITOR gating signals; a front-panel seven-segment display indicates the module code or fault code.
