Technical Specifications Applicable Platform: GE Series 90‑70 PLC rack Processing Function: Independent user‑defined coprocessor task execution On‑board Memory: Dedicated memory space for coprocessor application Backplane Interface: Series 90‑70 high‑speed backplane bus Operating Power: Supplied via 90‑70 rack backplane Operating Temperature: ‑40 ℃ to +70 ℃ Storage Temperature: ‑50 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Single‑slot plug‑in module for 90‑70 rack Certifications: CE, UL industrial control compliance
Functional Features Runs independent coprocessor application to offload complex calculation tasks from main CPU. High‑speed bidirectional data exchange with 90‑70 main CPU through backplane bus. On‑board memory stores coprocessor program and intermediate calculation data. Front‑panel LED status indicators show module running mode and fault alarm. Built‑in self‑diagnosis monitors hardware working status and reports faults to main CPU.
Application Scenarios Special data calculation for petrochemical and process‑control plants. High‑speed data processing for metallurgy heavy‑industry automation equipment. Performance expansion for large‑scale GE Series 90‑70 PLC control system. Industrial renovation projects requiring additional custom arithmetic functions.
Structural Characteristics Standard single‑slot plug‑in structure compatible with GE 90‑70 rack. Front‑panel LED indicator lamps for module status and fault prompt. Backplane golden‑finger interface for high‑speed data transmission and power supply.
Working Principle After obtaining power supply from rack backplane bus, the module executes loaded coprocessor application program. It receives raw data sent by main CPU via backplane bus, completes preset special computing logic, and returns processed result data to main controller.
Installation Requirements Install module into designated slot of GE Series 90‑70 standard rack. Strictly implement rack protective grounding according to official grounding specification. Complete module configuration and program download by official supporting software before commissioning. Ambient operating environment shall stay within defined temperature and humidity range without condensed moisture.
