PACSystems RX3i GE Fanuc IC695ALG704 Analog Output Modules

Product Overview

Configured for precise analog signal generation in PACSystems RX3i automation architectures, the GE Fanuc IC695ALG704 (IC695ALG704 Analog Output Module) provides direct physical/electrical execution. It transforms internal digital values into independent analog current or voltage signals to control field actuators, control valves, positioners, and variable speed drives.

Hardware Specifications

Industrial Control & Deterministic Backplane Communication

The module utilizes a high-velocity bus interface to exchange data synchronously with the main central processing unit over the universal backplane. The I/O density scaling and channel parameters are configured completely via corporate programming software, eliminating any hardware jumper mechanisms. This hardware supports seamless firmware flash compatibility, enabling infield upgrades via the RX3i CPU interface to ensure ongoing alignment with deterministic network controller architectures like Profinet and EtherNet/IP.

Frequently Asked Questions

Q: What are the specific firmware requirements for the controller when using this module? A: The module requires an RX3i central processing unit running firmware version 3.0 or later to execute configuration and data mapping routines.

Q: Can this module be hot-swapped while the universal backplane is energized? A: Yes, the RX3i platform supports Hot Insertion and Removal (Hot-Swap) capabilities under power, provided that the system configuration permits online module substitution and proper installation procedures are maintained.

Field Installation Guidelines

• Backplane Insertion: The module must be locked securely into a single slot of an RX3i Universal Backplane (IC695CHSxxx). Ensure the alignment connectors engage fully without applying excessive force.
• Terminal Block Compatibility: Use dedicated high-density terminal blocks such as Box-style (IC694TBB032) or Spring-style (IC694TBS032). For shielded wiring topologies, Extended Box-style (IC694TBB132) or Extended Spring-style (IC694TBS132) must be applied to accommodate the shroud depth.
• Shielding and Grounding: All instrumentation cables must use twisted-pair shielded conductors. Connect the cable shield to the ground terminal bar at the controller end only to mitigate ground loops and maximize high-frequency noise rejection.
• External Power Routing: Wire the external 24 VDC nominal power supply directly to the assigned terminal block points to drive the analog output circuitry. Keep DC signal cables separate from high-voltage AC routing to suppress capacitive cross-talk.
