Technical Specifications:
Series: GE Fanuc 90-70 VersaGen I/O
Channel Count: 6 channels, 24V DC sink/source inputs
Input Voltage: 12-24V DC (Configurable as PNP or NPN)
Input Filter: 0.1ms to 100ms (Software configurable per channel)
Diagnostic LEDs: Per-channel green LED for input status
Backplane: VMEbus
Isolation: 500V DC channel-to-backplane
Operating Temperature: 0°C to +60°C
MTBF: > 150,000 hours
Functional Features:
Per-Channel Diagnostics: Each of the 6 input channels has its own LED, allowing instant visual identification of which sensor is active or faulted.
Configurable Filtering: Each channel can have its own digital debounce filter (0.1ms to 100ms) to eliminate contact bounce or noise.
Sink/Source Selectable: Each input can be configured as either PNP (sourcing) or NPN (sinking) via software, eliminating the need for external wiring changes.
Wire-Break Detection: The module can detect if an input wire is broken (open circuit) and report the fault to the CPU.
Short-Circuit Protection: Each input is protected against short circuits to ground or to 24V.
Hot Swappable: Can be replaced while the PLC is running (with proper configuration).
Performance Parameters:
Input Response Time: < 1ms (with minimum filter)
Current per Channel: < 3mA (typical input current)
Isolation Voltage: 500V DC (Input to backplane)
Common Mode Rejection: > 60dB
Material Composition:
