The GE Fanuc IC670GB1002, also cataloged as the IC670GB1002 Digital Input Module, operates as a dedicated hardware component for processing 16-channel discrete digital input signals within Field Control and RX3i-compatible industrial automation platforms.

Hardware Specifications

Industrial Control Backplane Integration

The module is engineered for high-density signal acquisition within GE Fanuc architecture. Integration requires synchronization with the system Bus Interface Unit (BIU). Firmware flash compatibility and backplane bus communication velocity are determining factors for the effective scan cycle of the input data. The module supports both dry contact and voltage-based sensing, requiring the internal circuitry to maintain high input impedance while filtering transients to ensure deterministic input states. Proper I/O density scaling is managed through the Field Control mounting base, which also acts as the distribution point for the 120 VAC supply common to the module points.

Frequently Asked Questions

Q: Does the IC670GB1002 support both dry contact and voltage inputs?

A: Yes, the input circuitry is designed to interface with both dry contact closure signals and 120 VAC voltage signals, providing versatility for various field sensor types.

Q: What is the maximum latency for input state changes?

A: The module exhibits a typical response time of 10 ms, with a maximum latency of 20 ms, which must be accounted for in the system logic scan time.

Q: Is this module compatible with RX3i series systems?

A: The IC670GB1002 is compatible with GE Fanuc RX3i series control systems when utilized within the appropriate Field Control I/O rack or remote drops.

Field Installation Guidelines

• Mounting: Install the module onto a compatible Field Control I/O terminal base. Ensure the mechanical latches are locked to maintain electrical continuity with the backplane bus.
• Wiring: Terminate 120 VAC input wiring according to the local electrical code. Ensure that common neutral or hot lines are correctly phased if multiple input groups are shared across terminal bases.
• Grounding: To prevent noise-induced false triggering, ensure the DIN rail or mounting chassis is bonded to a low-impedance earth ground.
• Temperature Management: The module is rated for 0 deg C to 60 deg C. In high-density cabinet layouts, ensure adequate vertical clearance and convective cooling paths to prevent thermal degradation of the input components.
