Procure now IC693ALG391 GE Fanuc Analog Output Module
The IC693ALG391 is a highly precise 2-Channel Analog Output Module engineered by GE Fanuc for the robust Series 90-30 Programmable Logic Controller (PLC) family. This module is designed to provide high-resolution analog control signals to field devices such as variable frequency drives (VFDs), proportional valves, chart recorders, and other analog-driven industrial actuators. Capable of outputting both voltage and current signals, it supports standard industrial ranges including 0 to 10 VDC, -10 to +10 VDC, 0 to 20 mA, and 4 to 20 mA. The IC693ALG391 ensures rapid signal processing with an impressive update rate, guaranteeing seamless and accurate synchronization in demanding automated control loops.

Expert Tips for Installation and Shielding
When installing the IC693ALG391, mitigating electromagnetic interference (EMI) is the most critical factor for maintaining analog signal integrity. We highly recommend using twisted-pair, properly shielded cables for all field wiring connected to the module’s terminal block. The cable shield must be grounded at one end only—preferably at the PLC chassis ground—to avoid ground loops that can induce electrical noise and corrupt the analog output values. Furthermore, ensure that the analog cables are routed in separate conduits away from high-voltage AC lines or motor power cables.
Maintenance and Configuration Advice
Configuration of the IC693ALG391 is handled entirely through the PLC software (such as VersaPro, Proficy Machine Edition, or Logicmaster 90). Maintenance is generally minimal, but routine checks should include verifying the tightness of the terminal block screws and monitoring the 5 VDC backplane power supply levels, as voltage drops can affect analog accuracy. Periodic calibration verification against a certified digital multimeter is advised for applications requiring strict ISO quality compliance.

Frequently Asked Questions (FAQs)
Q: Does the IC693ALG391 require an external power supply?
A: No, the module draws its necessary operating power directly from the 5 VDC bus on the Series 90-30 backplane, simplifying the wiring architecture.
Q: Can I use one channel for voltage and the other for current simultaneously?
A: Yes, each of the two channels can be independently configured and wired for either voltage or current output according to the needs of the connected field devices.
