The IC694ALG390 is a compact analog output module designed for the GE Fanuc RX3i PacSystems series. This module provides two (2) output channels that convert binary digital data into precise analog voltage signals. Specifically, it supports an output range of -10 to +10 Volts, making it suitable for driving actuators, valves, recorders, and other analog field instruments.
Although it offers only two channels, the GE Fanuc IC694ALG390 delivers reliable performance with 13-bit resolution. Furthermore, it works seamlessly with all RX3i CPUs and fits into both RX3i serial expansion backplanes and Series 90-30 expansion backplanes. This flexibility makes it a practical choice for system upgrades or mixed-platform installations.
The IC694ALG390 operates with a 13-bit digital-to-analog conversion, ensuring smooth and accurate output signals. Both channels update simultaneously during each scan cycle, providing synchronized control for paired devices. The output voltage range of -10V to +10V covers most standard industrial analog requirements.
Power consumption is modest. At 5 VDC, the module draws 32 mA (0.16 W), while at 24 VDC isolated, it consumes 120 mA (2.88 W). These low power demands reduce the load on your system's power supply. The module is compatible with all RX3i CPUs, so you do not need to check firmware versions before installation.
Additionally, the GE Fanuc IC694ALG390 can be placed in any available I/O slot within the backplane. However, it does not support hot-swapping. Therefore, you must power down the entire rack before inserting or removing this module. Attempting to hot-swap may cause permanent damage to the module, the backplane, or the CPU, and could even create safety hazards for personnel.
The IC694ALG390 shares the same rugged environmental specifications as other RX3i modules. Its operating temperature ranges from 0°C to 60°C, while storage allows -40°C to 85°C. Humidity tolerance spans 5% to 95% non-condensing, enabling deployment in humid production areas.
Moreover, the module withstands vibration of 1G at 40 to 150 Hz and shock of 15G for 11 milliseconds. These mechanical ratings ensure stable operation in environments with moderate vibration, such as near compressors or conveyors. The compact design occupies one slot, leaving room for additional I/O modules in the same rack.
Installing the GE Fanuc IC694ALG390 requires careful planning due to the no-hot-swap restriction. First, ensure the entire system is powered off before opening the rack. Next, select an available I/O slot in either an RX3i serial expansion backplane or a Series 90-30 expansion backplane. Align the module with the card guides and slide it in firmly until the connectors seat properly.
After installation, connect your field devices to the two output terminals using shielded twisted-pair cables to minimize electrical noise. Then, configure the output range and scaling in your programming software. The module accepts 13-bit binary values, typically mapped to the -10V to +10V range. Double-check your wiring polarity, because reverse connections may produce incorrect output signals.
Finally, power on the system and verify output voltages with a multimeter. If the readings deviate from expected values, review your configuration and wiring. Remember, you must power down again before removing or repositioning the IC694ALG390. Following these steps ensures safe operation and prevents unnecessary downtime.

1. Can I install the IC694ALG390 while the system is running?
No. The GE Fanuc IC694ALG390 does not support hot-swapping. You must power off the entire backplane before inserting or removing this module to avoid damage or injury.
2. What backplanes are compatible with this module?
The IC694ALG390 works with both RX3i serial expansion backplanes and Series 90-30 expansion backplanes. It also supports all RX3i CPUs, giving you broad compatibility.
3. What is the output resolution of this module?
The module uses 13-bit digital-to-analog conversion. This provides fine granularity for the -10V to +10V output range, suitable for precise analog control applications.
4. How much power does the IC694ALG390 consume?
At 5 VDC, it draws 32 mA (0.16 W). At 24 VDC isolated, it draws 120 mA (2.88 W). These values are relatively low, so most standard power supplies can handle multiple modules.
5. Can I use this module with a Series 90-30 CPU?
While the IC694ALG390 fits into Series 90-30 backplanes, it requires an RX3i CPU for proper operation. It is not designed to work with Series 90-30 CPUs directly.
