GE 0517L0325BB-G001
- Product Name: GE Mark V/VI 32-Channel Digital Input Module
- Overview: This module belongs to the GE Speedtronic Mark V/VI control system and serves as a standard module for collecting external discrete signals such as pushbuttons, limit switches, relay contacts, and proximity switches.
- Technical Specifications:
- Input Channels: 32 channels
Detailed content
-
- Input Type: 24 V DC sourcing/sinking (configurable)
- Input Voltage Range: 12–28 V DC (logic high)
- Input Current: ≤ 5 mA per channel
- Optical Isolation: 4 groups, fully isolated every 8 channels
- Communication: VMEbus
- Mounting: 19-inch cabinet plug-in
- Response Time: ≤ 1 ms
- Isolation Voltage: 1500 V DC
- Insulation Resistance: ≥ 100 MΩ at 500 V DC
- Operating Temperature: 0 °C to 60 °C
- Humidity: 5 %–95 % non-condensing
- Material & Structure: Aluminum alloy die-cast housing with anodized finish; FR-4 multilayer PCB with moisture-proof coating; gold-plated pin connectors; Toshiba TLP281 or equivalent industrial optocouplers.
- Functional Features: High-density 32-channel design saves cabinet space; 4 independent isolated groups enhance anti-interference capability; supports dry-contact input; built-in LED for each channel status; software-configurable debounce filtering (1–100 ms).
- Working Principle: External discrete signals enter the module through input terminals, pass through optocoupler isolation, and are latched by FPGA/CPLD logic chips. The controller reads the 32-bit input status word via the VMEbus.
- Applications: Thermal power generation, gas turbines, water treatment, industrial process control.
- Installation Requirements: Shielded cables must be used for external dry-contact signals; sourcing/sinking mode is set via top jumpers; terminal screw torque 0.5–0.8 N·m.
- Usage Notes: Input voltage must not exceed 28 V DC to avoid optocoupler damage; RC snubbers are required for inductive load inputs; unused input channels must be tied to a defined level to avoid floating.
