GE IC694ALG390C RX3i 2-Channel Analog Voltage Output Module
Two-channel analog voltage output module for command and setpoint signals in PACSystems RX3i systems.
Description and purpose
The requested nameplate is IC694ALG390C. GE's official RX3i documentation identifies the base IC694ALG390 as a two-channel analog voltage output module. Each channel provides a −10 to +10 V command signal with 2.5 mV per count resolution; the approximate update time for both channels is 5 ms and is application dependent.
The output load is limited to 5 mA, requiring at least 2 kΩ, and the module uses 32 mA from the +5 VDC supply plus 120 mA from the isolated +24 VDC supply. Treat C as part of the complete nameplate and verify it against project records; do not infer interchangeability from the IC694ALG390 base number alone.
Technical specifications
Values summarized from GE IC694ALG390 analog-output documentation and PACSystems RX3i hardware references. Final selection must follow the complete catalog number and installed system.
Need to replace a two-channel voltage card without disturbing the process?
Send Myrtle the complete IC694ALG390C label, terminal-block photo, receiving-device input resistance, channel wiring, rack details, quantity and destination. We will compare the request with the official −10 to +10 V range, 5 mA load limit, power requirements and project scaling before quotation.
Applications
Drive references, actuator commands, analog setpoints, test equipment and compact process skids requiring two voltage output channels in an RX3i installation.
Ordering information
Product image and identification notes

Confirm the voltage-output legend and wiring evidence
Request front, side and terminal photographs that clearly show IC694ALG390C and both voltage-output channels. Verify the removable terminal block, channel commons, backplane contacts and any heat damage. Compare the photo with the official −10 to +10 V wiring because the current-output IC694ALG391 is a different module even though the housings may appear similar.
