Features:
- Provides sixteen AutoMax/DCS 5000 module positions in a panel-mounted rack.
- Uses the documented P1 and P2 backplane bus architecture.
- Includes line filtering and dual-fan cooling for the installed module set.
Catalog number 57C331 identifies the sixteen-slot panel rack for AutoMax and DCS 5000 hardware.
Its P1 and modified P2 backplanes distribute power and intermodule signals to the installed control assembly.
Plan cabinet support, line filtering, fan airflow and processor-family compatibility before rack replacement.
