The IC697VDD100 is a 64‑point, 24 VDC source digital input module for GE Fanuc’s Series 90‑70 / PACSystems RX7i PLC platform.

Key specifications

• Function: Digital input module (discrete inputs)
• I/O capacity: 64 individual input points on one board
• Input type / voltage: 24 VDC source, typical operating range around 5–250 VDC sensing capability per channel in some documentation
• Isolation: 64 optically isolated inputs with high channel‑to‑channel and channel‑to‑logic isolation (typically 1000 VDC / 700 VRMS class)
• Intelligent features: Can be configured for Sequence‑of‑Events (SOE) recording, useful in safety and event‑logging applications
• Platform: Used in GE Fanuc Series 90‑70 and PACSystems RX7i controllers, installed in the VME‑style backplane/rack
• Typical use cases: High‑density status monitoring of field devices (limit switches, sensors, relay contacts, etc.) where many 24 VDC signals must be read reliably in a single slot

Some distributor pages list it generically as a “digital input module” or “PLC module/rack” without full electrical details, but the GE/Fanuc documentation consistently describes it as a 64‑channel isolated 24 VDC source input board with SOE capability.

Typical sourcing / replacement notes

• This is a legacy GE Fanuc part; new stock is usually from specialist distributors or surplus/repair vendors rather than mainstream automation suppliers.
• When sourcing, confirm:
  • That it’s specified for Series 90‑70 / RX7i (not RX3i or other families).
  • Whether you need SOE functionality and that your CPU/firmware supports it.
  • Condition (new, refurbished, used) and whether it’s tested, especially for critical applications.
