Working Principle Module connects to Series 90‑70 backplane bus and matched coprocessor daughter‑board. It completes bus signal level conversion and signal buffering. Realizes data exchange between main CPU and coprocessor hardware, distributes auxiliary power supply for coprocessor unit, feeds back link fault status via LED indicators.
Installation Requirements Insert module into available slot of Series 90‑70 chassis. Complete control cabinet protective grounding. Install matched coprocessor daughter‑board correctly. Power‑off rack before module installation or removal. Ensure cabinet ventilation and heat dissipation.
Usage Notes Only compatible with Series 90‑70 series hardware. Confirm coprocessor daughter‑board model matching. Observe LED status for link fault diagnosis. On‑site disassembly is prohibited. Avoid corrosive gas and liquid splash.
