GE IC697ALG230 (44A720772-G01) Analog Output Module | Series 90-70 PLC Platform
Engineering Background
The GE IC697ALG230, part number 44A720772-G01, is a high-precision 8-channel analog output module engineered for the GE Series 90-70 Programmable Logic Controller (PLC) platform — one of the most widely deployed rack-based control architectures in heavy industry. Designed to GE Fanuc’s stringent manufacturing standards, this module delivers deterministic analog signal conditioning for process control loops requiring reliable voltage and current output across demanding industrial environments.
Product Positioning
Targeted at procurement engineers and MRO specialists managing legacy Series 90-70 installations, the IC697ALG230 provides a direct OEM-equivalent replacement path with no firmware reconfiguration required. It is the preferred choice for facilities in petrochemical, power generation, water treatment, and discrete manufacturing sectors where downtime cost far exceeds component cost.

Proven Application Environments
- Petrochemical & Refining: Valve positioner control, flow regulation loops, and pressure setpoint transmission in hazardous-area adjacent panels.
- Power Generation: Turbine governor analog setpoints, excitation control signal output, and boiler feed control.
- Water & Wastewater Treatment: Pump speed reference via VFD analog input, chemical dosing control, and level control loops.
- Automotive & Discrete Manufacturing: Servo drive analog command signals, conveyor speed control, and press force regulation.
- Pulp & Paper / Food & Beverage: Temperature setpoint output to PID controllers, tension control, and batch process analog command.
Engineering Advantages
- Dual-mode output: Configurable per channel for voltage (±10 V) or current (4–20 mA) without hardware modification — reduces BOM complexity.
- 12-bit resolution: Provides 0.024% full-scale accuracy, meeting ISA-5.1 signal fidelity requirements for closed-loop process control.
- Hot-swap compatible: Supports Series 90-70 hot-standby configurations, enabling module replacement without full system shutdown.
- Direct OEM replacement: No ladder logic changes or I/O table reconfiguration required when replacing a failed IC697ALG230 unit.
- Backplane-powered: Eliminates external 24 VDC power supply requirement for the output stage, simplifying panel design.
System Architecture & Signal Flow
The IC697ALG230 occupies a single slot in any Series 90-70 rack (5-slot, 9-slot, or 12-slot chassis). The CPU communicates with the module via the Series 90-70 VME-based backplane at each PLC scan cycle. The module’s internal DAC converts the 12-bit digital word from the CPU output table into a proportional analog signal on each of the 8 output channels. Field wiring connects to the module’s front-face terminal block, with each channel independently configurable via the GE Proficy Machine Edition (PME) or Logicmaster 90-70 programming environment.

Technical FAQ
Q: Is the IC697ALG230 compatible with the IC697CPU788 redundant CPU?
A: Yes. The IC697ALG230 is fully compatible with all Series 90-70 CPUs including the IC697CPU788 hot-standby redundancy configuration.
Q: Can I mix voltage and current output channels on the same module?
A: Yes. Each of the 8 channels is independently configurable for either ±10 V or 4–20 mA output via the software configuration tool (PME or LM90).
Q: What is the difference between IC697ALG230 and IC697ALG233?
A: The IC697ALG233 is a 16-channel variant. The IC697ALG230 provides 8 channels. Both share the same backplane interface and configuration methodology.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC and functional test report are available upon request at time of order.
Q: What programming software is required to configure this module?
A: GE Proficy Machine Edition (PME) v8.0+ or Logicmaster 90-70 v9.05+. No special license is required beyond standard Series 90-70 I/O configuration.
