Product Introduction & Supply Chain Strategy
The GE Fanuc / Emerson IC697ALG230 is an 8-channel high-level analog input module engineered for Series 90-70 programmable logic controllers. It converts real-world process signals—such as 4–20 mA current loops and ±10 V signals from pressure, flow, and temperature transmitters—into 12-bit binary data for high-speed processing across VME backplanes.
Since the GE Series 90-70 platform has reached End of Life (EOL), sourcing the IC697ALG230 as New Surplus is a critical strategic supply chain move. Refurbished analog modules often suffer from component drift, aging operational amplifiers, and thermal degradation that lead to signal measurement errors. Stocking genuine New Surplus inventory eliminates these failure vectors, providing long-term reliability and guarding against unexpected plant outages without requiring a complete control system migration.
Installation & Configuration Guide
1.Pre-Installation (Prep & Safety):Safety measures and environment preparation.
Isolate all rack power sources using strict LOTO standards. Put on an anti-static ESD wrist strap connected to cabinet earth ground before handling the IC697ALG230. Label all wiring connections on the removable terminal board and document current DIP switch configurations.
2.Removal:Disconnecting wiring and module extraction.
Loosen the top and bottom captive screws holding the removable terminal block to disconnect field wiring without altering the leads. Unlatch the top and bottom module locking tabs on the Series 90-70 rack frame. Slide the old IC697ALG230 card straight forward along the guide rails to prevent bending the VME bus backplane pins.
3.Installation (Clone & Seat):Hardware configuration and installation.
Set the jumper positions on the new IC697ALG230 to mirror the input selection (Voltage vs. Current) of the original unit. Align the card with the upper and lower rack guides of the designated slot. Push the module firmly into the VME backplane until the retention latches click, then reattach the wired terminal block.
4.Power-On & Testing:Power sequence and diagnostic checks.
Re-energize the rack assembly and monitor the front-panel status LEDs. The MODULE OK light must glow solid green. Connect using Proficy Machine Edition or Logicmaster 90, upload hardware configuration data, and measure 4–20 mA loop values with a calibrated meter to verify input accuracy.

Firmware/Software Versions & Upgrade Notes
- Software Compatibility: Fully supported by Logicmaster 90-70, Control 90-70, and Proficy Machine Edition (PME) across all release versions.
- Jumper Configuration Note: Hardware jumpers on the IC697ALG230 select voltage or current mode per channel group. Mismatched jumper settings relative to the software configuration in PME will cause incorrect scaling values and channel fault flags.
- Legacy Bus Caution: When substituting the into older Series 90-70 racks, ensure that backplane DIP switch addresses match the assigned CPU memory registers to prevent I/O mapping conflicts.
Frequently Asked Questions (FAQ)
Is the completely new and unused?
Yes. This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Original packaging is opened solely for visual inspection and anti-counterfeit serial verification.
Why buy a New Surplus instead of a refurbished card?
Refurbished analog modules frequently suffer from signal drift caused by aged resistors and degraded analog-to-digital converter components. A bad reading of just 1% on a critical pressure loop can throw off an entire batching process. Buying New Surplus ensures factory-spec accuracy and long operational life.
How do I configure the for a 4-20 mA current loop?
The accepts direct voltage inputs natively. To read a 4–20 mA current loop, a precision 250 Ω resistor must be wired across the input terminals, converting the 4–20 mA signal into a 1–5 VDC input for the module’s A/D converter.
Is the Series 90-70 system obsolete, and how does this affect my spares strategy?
Yes, the GE Series 90-70 platform is obsolete. Because OEM factory support has ended, plants using this hardware should hold 1 to 2 units of critical cards like the on-site as buffer stock. Strategic hoarding of New Surplus cards prevents emergency shutdowns while migration projects are planned.
Can the be inserted while the rack is powered?
No. The Series 90-70 VME backplane does not support Hot-Swapping (Removal and Insertion Under Power). Attempting to remove or insert the while power is applied can arc backplane pins, corrupt CPU RAM, or permanently damage the module.
What warranty is provided with this New Surplus analog module?
We support this with a comprehensive 1-year functional replacement warranty. If any channel accuracy fault or hardware defect occurs during normal operation within 12 months, we will immediately supply a replacement module from our stock.
