GE IC694ALG392 8-Channel Analog Output Module
Product Introduction
The IC694ALG392 is an 8-channel, 12-bit analog output module in GE’s Series 90-30 PLC family. It provides isolated current outputs (0–20 mA or 4–20 mA) with software-selectable ranges for interfacing with control valves, actuators, recorders, and other field devices. The module communicates over the high-speed Series 90-30 backplane, delivering deterministic update rates and tight loop control for demanding process applications.
Key Applications
-
Precise positioning of control valves and dampers in oil & gas and petrochemical plants.
-
Driving proportional actuators in batch reactors and continuous chemical processes.
-
Supplying analog reference signals to chart recorders and data acquisition systems in utilities.
-
Integrating with distributed I/O skids in water/wastewater treatment for pump and valve control.
-
Coordinating motion control and servo drives in packaging, material handling, and automotive assembly.
Brand and Series Overview
Brand: GE Automation & Controls
Series: 90-30 PLC I/O Modules
GE Automation & Controls, a division of General Electric, has delivered the Series 90-30 PLC platform for over two decades, supporting critical infrastructure and process industries with rugged hardware and long-lifecycle support.
Product Advantages
-
Isolated Outputs: Each of eight channels is galvanically isolated (500 V DC) to prevent ground‐loop errors and ensure signal integrity.
-
Flexible Ranges: Software-configurable current outputs of 0–20 mA or 4–20 mA without hardware changes.
-
Deterministic Performance: Typical update scan of all channels in <20 ms ensures real-time responsiveness.
-
Robust Design: Operates from –25 °C to +70 °C with conformal-coated PCB for harsh environments.
-
Seamless Integration: Plug-and-play module installs into any 90-30 backplane slot with no jumpers or switches.

Frequently Asked Questions (FAQ)
Q: What output ranges does the IC694ALG392 support?
A: Each channel supports 0–20 mA or 4–20 mA current ranges, selectable via software configuration.
Q: How isolated are the outputs?
A: Outputs are isolated to 500 V DC between channels and to the backplane to prevent noise and ground loops.
Q: What is the update time for all eight channels?
A: The module updates all channels in under 20 ms, suitable for tight control loops.
Q: Can it drive voltage outputs?
A: No; this module is current-output only. For voltage outputs, see module IC694ALG393.
Q: What environmental conditions can it endure?
A: Operates from –25 °C to +70 °C and 5 %–95 % RH (non-condensing), with conformal coating for corrosion resistance.
Q: How is the module configured?
A: No jumpers or switches—configuration is managed through the PLC’s I/O configuration tool.
Q: Is enhanced resolution available?
A: This module is fixed at 12-bit resolution; for 14-bit resolution, consider IC694ALG391.
Q: What PLC platforms are compatible?
A: Designed for GE Series 90-30 backplanes; not compatible with RX3i slots.
Q: How do I mount the module?
A: It slides into any available slot on a 90-30 baseplate rail and locks with the integral latch.
Q: What certifications does it hold?
A: CE, UL, and cUL approvals for industrial control equipment.
