GE Fanuc IC693ALG392 Series 90-30 Analog Output Module
The GE Fanuc IC693ALG392B, also cataloged as the IC693ALG392 Analog Output Module, serves as the primary IC693ALG392 Analog Output Module utilized to execute digital-to-analog signal conversion across Series 90-30 and PACSystems RX3i platforms. The hardware provides 8 analog output channels configurable to generate regulated current loops or voltage gradients for driving control valves, variable speed drive references, or strip chart recorders. It interfaces directly with the backplane parallel bus to receive updated digital values from the central processing unit during each I/O scan cycle.

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling
The IC693ALG392B operates with low internal propagation delays to maintain response linearity when linked through remote chassis interfaces. When output command structures are distributed over upstream Profinet or EtherNet/IP deterministic networks, the module updates its internal digital-to-analog registers within predictable clock windows, preventing control loop oscillations. This multi-range architecture facilitates efficient I/O density scaling on modular backplanes while ensuring total firmware flash compatibility with both legacy Series 90-30 CPUs and contemporary PACSystems controllers.
Frequently Asked Questions
Q: Does the IC693ALG392B support hot-swap insertion and removal while the backplane is energized?
A: No. The underlying Series 90-30 backplane interface does not incorporate power-limiting trace configurations for live extraction. Swapping the module while under electrical load risks inducing logic bus disruption, processor faults, or permanent component degradation across the backplane interface.
Q: What is the behavior of the analog output channels if the module loses communication with the CPU?
A: The outputs can be configured to hold their last state or default to zero. This fallback behavior is defined in the configuration software and is independent of the external 24 VDC loop excitation voltage, maintaining predictable field device positioning during fault mitigation.
Field Installation Guidelines
- Chassis Slot Selection: Ensure all power sources to the backplane are fully isolated. Hook the top hinge of the module into the upper slot index on the baseplate, pivot the assembly downward until the multi-pin connector mates securely with the backplane, and tighten the retaining screw.
- External Power Allocation: A dedicated, filtered 24 VDC field excitation supply must be connected to the terminal block to power the internal analog drive circuitry. Separate the loop supply cabling from high-voltage AC source lines to eliminate electromagnetic inductive coupling.
- Shield Grounding and Routing: All analog command loops must utilize twisted, fully shielded pair conductors. Terminate the shield braid exclusively at the chassis earth ground bar on the module end. Keep the field actuator side of the shield ungrounded to prevent circulating ground loops from destabilizing the 12-bit resolution signals.
