GE IC693ALG391 – Mixed Analog I/O Module | GE Fanuc Series 90-30 Platform
Engineering Background
The IC693ALG391 is a mixed analog input/output module designed for the GE Fanuc Series 90-30 PLC platform — one of the most widely deployed mid-range control architectures in discrete and process manufacturing. Engineered to bridge field-level analog signals with the Series 90-30 CPU backplane, this module delivers reliable, high-resolution signal conditioning for both sensing and actuation loops in a single slot footprint.
Product Positioning
Targeting procurement engineers and controls integrators who require a verified, drop-in replacement or expansion module for existing Series 90-30 installations, the IC693ALG391 eliminates the need for external signal converters by combining analog inputs and outputs in one compact module. It is the preferred choice for OEM machine builders and plant maintenance teams managing legacy GE Fanuc control systems.

System Architecture & Signal Flow
The IC693ALG391 occupies a single slot in any Series 90-30 5-slot, 10-slot, or expansion chassis. Field wiring connects to the module’s removable terminal block. Analog input signals are sampled, converted by the 12-bit ADC, and written to the CPU’s %AI reference table each scan. Analog output values are read from the CPU’s %AQ reference table and converted by the 12-bit DAC to drive field actuators. The optical isolation barrier separates field commons from the backplane 5 VDC logic supply, ensuring signal integrity across mixed-ground industrial installations.
Signal path: Field Instrument → Terminal Block → Input Conditioning → 12-bit ADC → Backplane Bus → CPU %AI Table
Output path: CPU %AQ Table → Backplane Bus → 12-bit DAC → Output Driver → Terminal Block → Field Actuator

Technical FAQ
Q: Is the IC693ALG391 compatible with the IC693CPU374 (Ethernet CPU)?
A: Yes. The IC693ALG391 is compatible with all Series 90-30 CPUs including the IC693CPU374, as analog I/O modules communicate via the backplane bus independent of the CPU’s communication interface.
Q: Can I mix current and voltage inputs on the same module?
A: Yes. Each input channel is independently configurable via jumper for either current (4–20 mA) or voltage (0–10 V / ±10 V) input ranges.
Q: What is the scan time impact of adding this module?
A: Analog I/O modules in the Series 90-30 are scanned asynchronously from the CPU logic scan. The IC693ALG391 updates its I/O values each backplane scan cycle, typically adding less than 1 ms to overall system scan time.
Q: Is a replacement terminal block available separately?
A: Yes. The removable terminal block for the IC693ALG391 is field-replaceable. Contact us for spare terminal block availability.
Q: Do you provide a warranty?
A: Yes. All modules sold through Konmask.com carry a 90-day functional warranty. Extended warranty options are available — contact us for details.
