IC695ALG616-DA GE RX3i 24-Bit 16-Channel Analog Input Card

GE IC695ALG616-DA PACSystems RX3i Analog Input Module

The GE IC695ALG616-DA, also cataloged as the IC695ALG616 Analog Input Module, operates as a dedicated hardware component for multi-channel process variable data acquisition within PACSystems RX3i platforms. The card interfaces directly with raw industrial field signals, routing either 16 single-ended or 8 differential analog circuits into the central computing framework. The module executes signal sampling through an integrated 24-bit analog-to-digital converter core, which translates variable voltage and current loops into numerical register values for real-time calculation by the host controller.

Hardware Specifications

I/O Density Scaling and Backplane Bus Communication Velocity

The IC695ALG616-DA facilitates high-density scaling across the PACSystems local backplane by optimizing multi-channel mapping within a single rack slot footprint. To preserve measurement synchronization, the on-board conversion hardware coordinates data package arrays to match the backplane bus communication velocity licenses of the RX3i chassis. The system executes channel filtering and gain calibration through proprietary logic that features absolute firmware flash compatibility with contemporary CPU modules. This high-speed pipeline translates field values instantly into standard memory words, preventing phase errors during sudden industrial process loop step-changes.

Frequently Asked Questions

Q: How does the non-isolated channel architecture of the IC695ALG616-DA affect common-mode voltage limits?

A: Because the module utilizes a non-isolated input structure, all field signaling return lines share a common electrical reference point on the board assembly. Personnel must ensure that the voltage differential between adjacent channels remains within technical reference parameters to avoid signal saturation or thermal failure of the input matrix.

Q: What are the restrictions regarding live insertion or hot-swapping the IC695ALG616-DA within an active RX3i system?

A: The PACSystems RX3i backplane platform permits hot-swapping under exact electrical guidelines. The module can be extracted or replaced while backplane power is active, provided that the field wiring terminal block is disconnected first to prevent ungrounded current surges from interrupting neighboring I/O communications.

Field Installation Guidelines

• Module Insertion Mechanics: Slide the circuit card assembly smoothly into the designated chassis slot until the integrated rear connectors seat completely into the active backplane. Secure the mechanical module latches to ensure solid retention and electrical grounding continuity.
• Signal Line Shielding: Install twisted-shielded pair conductors for all analog current and voltage loops. Terminate the individual cable drain wires directly to the external chassis grounding bar, keeping the unshielded wire exposure minimal near the terminal screws.
• Conductor Separation Routing: Maintain physical separation between the low-voltage analog input signal lines and high-voltage AC electrical distribution runs within the panel enclosure to prevent inductive noise coupling.
