Technical Specifications PLC Compatibility: GE Series‑90‑30 PLC Slot Quantity: 10 module slots Backplane: Series‑90‑30 expansion backplane bus Mounting: DIN‑rail or cabinet panel mounting Operating Temperature Range: 0 ℃ to +60 ℃ Storage Temperature Range: ‑40 ℃ to +85 ℃
Functional Features Provides mechanical mounting positions and backplane bus interconnection for Series‑90‑30 modules. Extends system module capacity independent of main CPU rack. Connectable to main rack via expansion cable. Distributes rack logic power to inserted modules.
Application Scenarios Series‑90‑30 PLC system I/O capacity expansion, automation cabinet multi‑rack layout, legacy control system renovation and spare‑part replacement.
Performance Parameters Total supported modules: 10 slots on single rack, subject to system power budget.
Structural Characteristics Metal industrial chassis housing. Internal gold‑plated backplane bus. Module retention latches for each slot. Expansion cable interface for linking to main rack. DIN‑rail mounting brackets.
Working Principle Expansion cable connects IC693CHS392 backplane bus with main CPU rack backplane. Control signals and data signals are transmitted between main rack and expansion rack. All modules inserted in this rack can communicate with Series‑90‑30 CPU through unified system bus.
Installation Requirements Securely mount chassis on DIN‑rail or cabinet panel. Use qualified Series‑90‑30 expansion cable to link with main rack. Calculate total power consumption of modules loaded on expansion rack. Reliable protective ground connection.
Usage Notes Do not exceed rack power supply load capacity. Use original matching expansion cable. Power off whole PLC system before plugging or removing modules.
