GE IC694ALG442 Multi-Function Analog I/O Module
Product Introduction
The IC694ALG442 is a versatile analog I/O module in GE’s PACSystems™ RX3i family. It combines four channels of configurable current or voltage input with four channels of configurable current or voltage output in a single 34 × 145 × 140 mm package. With 16-bit resolution, galvanic isolation, and diagnostic reporting, this module reduces panel footprint and inventory while delivering precise measurements and reliable control for complex process applications.
Key Applications
-
Process Feedback & Control: Measure and drive valve positions and flow controllers in oil & gas and petrochemical plants.
-
Batch Process Automation: Execute recipe-based input/output sequencing in chemical and pharmaceutical manufacturing.
-
Water & Wastewater Management: Monitor pH, level, and turbidity sensors while controlling chemical dosing pumps.
-
Power Generation: Acquire generator excitation feedback and provide governor control signals.
-
Machine & Motion Control: Interface with servo drives and proportional valves in packaging and material handling equipment.
Brand and Series Overview
Brand: GE Automation & Controls
Series: PACSystems™ RX3i I/O Modules
PACSystems RX3i modules deliver high performance, flexibility, and long lifecycle support for process and discrete control. The ALG442 leverages this platform’s high-speed backplane and advanced diagnostics to enhance system uptime and simplify maintenance.
Product Advantages
-
Multi-Function Flexibility: Four universal input and four universal output channels eliminate separate I/O types and reduce spare parts.
-
High Resolution & Accuracy: 16-bit A/D and D/A conversion yield ±0.05 % full-scale accuracy for both inputs and outputs.
-
Channel Isolation: 1500 V AC isolation between every input, output, and backplane prevents ground loops and noise coupling.
-
Built-In Diagnostics: Real-time status bits report open-wire, over-range, under-range, and module health to the PLC.
-
Space & Cost Savings: Combines eight functions in one slot, halving rack requirements and wiring compared to discrete I/O modules.

Frequently Asked Questions (FAQ)
Q: What makes the ALG442 “multi-function”?
A: It integrates four configurable inputs and four configurable outputs—current or voltage—into a single module, reducing spare parts and wiring.
Q: How accurate are the measurements?
A: Both inputs and outputs offer ±0.05 % full-scale accuracy with 16-bit resolution for precise process control.
Q: Can the inputs and outputs be mixed?
A: Yes—any input channel can be configured for voltage or current, and any output channel likewise, via software settings.
Q: How does the module report wiring faults?
A: Built-in diagnostics detect open-wire conditions on each channel and report status back to the PLC.
Q: Is electrical isolation provided?
A: Yes, 1500 V AC galvanic isolation between every channel and the backplane prevents ground-loop errors.
Q: What is the typical update time?
A: The module scans all eight channels in under 15 ms, delivering timely data for fast control loops.
Q: Which PLC series support this module?
A: It is compatible exclusively with the PACSystems RX3i backplane.
Q: What environmental conditions can it withstand?
A: Rated for –25 °C to +70 °C and 5 %–95 % RH (non-condensing), with conformal coating for harsh environments.
Q: How much rack space does it occupy?
A: It uses one RX3i I/O slot (34 mm wide) yet replaces two separate analog input and output modules.
Q: Does it support HART communication?
A: No, the ALG442 does not include HART; for HART-enabled outputs see IC695AOI622.
