GE Fanuc IC694ALG392-BB PACSystems RX3i Analog Output Module
The GE Fanuc IC694ALG392-BB, also cataloged as the IC694ALG392 Analog Output Module, operates as a dedicated hardware component for converting digital controller commands into high-precision current and voltage field signals within PACSystems RX3i racks. The module features 1 to 8 selectable single-ended output channels supporting ranges of 4 to 20 mA, 0 to 20 mA, 0 to 10 VDC, and -10 to +10 VDC. Driven by an update rate of 8 ms across all active channels, it drives actuators, control valves, motor drives, and positioning pistons directly from the PLC backplane interface.

Backplane Bus Communication and Firmware Flash Compatibility
The IC694ALG392-BB coordinates output signal conversion directly across the PACSystems RX3i backplane bus, transferring 16-bit register values to the onboard digital-to-analog converter (DAC) stage without compromising system backplane bus communication velocity. Full firmware flash compatibility enables seamless operation across both PACSystems RX3i and legacy Series 90-30 baseplates. The hardware draws 110 mA from the internal +5 VDC bus while using an external 24 VDC loop supply to drive high-density field loops and maintain channel precision across extended ambient temperature shifts.
Frequently Asked Questions
Q: What external power supply source is required to drive the output current loops on the IC694ALG392-BB?
A: The module requires an isolated external 24 VDC user power supply (voltage range 20 to 30 VDC) attached to the terminal block to power the current loops and voltage output drive circuitry.
Q: How does backplane power consumption scale when the module is fully populated?
A: The internal logic circuits draw a constant 110 mA at 5 VDC directly from the backplane bus, while all field output loop currents draw up to 315 mA from the separate external 24 VDC supply.
Q: Can the IC694ALG392-BB be installed in legacy Series 90-30 PLC expansion baseplates?
A: Yes, the module maintains dual backplane compatibility, permitting direct physical installation and logic control within both PACSystems RX3i and Series 90-30 systems.
Field Installation Guidelines
Ensure main chassis backplane power and external 24 VDC user power are fully de-energized before inserting or removing the IC694ALG392-BB module from the rack slot. Align the module housing with the baseplate guide slot and push firmly until the top and bottom latch mechanisms lock into place.
Route field wiring to the front terminal block using individually shielded twisted-pair cables for each output loop. Ground cable shields at a single point on the main enclosure earth ground bar, keeping low-level 4 to 20 mA and +/-10 VDC signal lines physically isolated from AC power distribution lines, motor leads, and variable frequency drive output conduits to minimize ambient noise pickup.
