GE IC670ALG240 Analog Current Input Module | Replacement, Equivalent & Selection Guide
The GE IC670ALG240 is a 16-channel analog current input module designed for the GE Series 90 Micro and Field Control distributed I/O systems. It accepts 4–20 mA current loop signals and converts them to digital values for PLC processing — making it a critical interface between field instruments (transmitters, sensors) and the control system. Whether you are maintaining an aging Series 90 Micro installation or sourcing a drop-in replacement for a failed module, this page provides the complete selection and compatibility reference you need.
At Konmask.com, we specialize in sourcing hard-to-find GE automation components. The IC670ALG240 is one of the most widely deployed analog input modules in the GE Field Control ecosystem, used across water treatment, oil & gas, chemical processing, and discrete manufacturing plants worldwide. Our team verifies authenticity and functionality before every shipment.

Compatible Replacement & Equivalent Models
When the IC670ALG240 is unavailable or discontinued, the following models may serve as functional replacements depending on your system configuration. Always verify electrical and firmware compatibility before substitution:
- IC670ALG240C — Revised hardware revision of the same module; direct drop-in replacement in most applications
- IC670ALG241 — 8-channel analog current input variant; suitable if channel count can be reduced
- IC670ALG620 — Analog combo module (input + output); consider if output capability is also needed
- IC693ALG222 — GE Series 90-30 analog input module; requires Series 90-30 rack, NOT a direct replacement but functionally similar for system redesign
- IC694ALG222 — PACSystems RX3i analog input; for system migration projects
- Third-party equivalents: Some Wago, Phoenix Contact, and Beckhoff analog input modules can interface with GE Field Control via gateway adapters — consult Konmask for integration support
Important: The IC670 Field Control family uses a proprietary bus. Replacement modules must be IC670-series compatible or connected via a certified gateway. Do not substitute with IC693 or IC694 modules directly into an IC670 carrier.
Why Choose the Original Model
- Proven field reliability: IC670ALG240 has decades of deployment history in mission-critical industrial environments
- Zero re-engineering cost: Drop-in replacement preserves existing wiring, carrier, and PLC program — no I/O mapping changes required
- Firmware compatibility: Guaranteed compatibility with existing GE Series 90 Micro CPU firmware versions
- Regulatory compliance: Maintains existing system certifications (CE, UL) without re-validation
- Reduced commissioning risk: No integration testing required when replacing like-for-like
Typical Applications
- Water & wastewater treatment — flow, pressure, and level transmitter inputs
- Oil & gas — wellhead monitoring, pipeline pressure sensing
- Chemical processing — temperature and concentration loop inputs
- Food & beverage — process variable monitoring in hygienic environments
- Power generation — turbine and boiler analog signal acquisition
- Discrete manufacturing — conveyor tension, force, and position sensing via 4–20 mA transmitters
System Compatibility
- Compatible CPUs: IC670CPU105, IC670CPU300, IC670CPU305 (Series 90 Micro)
- Required Carrier: IC670CHS002 or IC670CHS004 (Field Control I/O carrier)
- Bus Interface: IC670GBI001 Genius Bus Interface Unit
- Programming Software: GE Proficy Machine Edition (ME), Logicmaster 90 Micro
- NOT compatible with: IC693 Series 90-30 racks, IC694 RX3i racks, or VersaMax I/O directly
Selection Guide
Use the following decision matrix to select the correct module for your application:
- Need 16-ch 4–20 mA input, same IC670 carrier? → IC670ALG240 or IC670ALG240C (direct replacement)
- Need fewer channels to reduce cost? → IC670ALG241 (8-channel)
- Migrating to Series 90-30? → IC693ALG222 with new rack and CPU
- Migrating to PACSystems RX3i? → IC694ALG222 with RX3i backplane
- Need voltage input instead of current? → IC670ALG230 (analog voltage input module)
- Need combined analog I/O? → IC670ALG620

Replacement & Compatibility FAQ
Q: Can I use IC670ALG240C instead of IC670ALG240?
A: Yes. The “C” suffix denotes a hardware revision. It is functionally identical and a direct drop-in replacement in the same IC670 carrier without any program changes.
Q: Will IC670ALG240 work in a Series 90-30 (IC693) rack?
A: No. The IC670 series uses a Field Control bus and dedicated carriers. It is not physically or electrically compatible with IC693 Series 90-30 racks.
Q: My IC670ALG240 shows all channels reading 0 — is it failed?
A: Check the Field Control bus connection and carrier seating first. Also verify the Genius Bus Interface Unit (IC670GBI001) is powered and communicating. A failed module typically shows a fault LED; all-zero readings often indicate a wiring or bus configuration issue.
Q: Do you supply new or refurbished units?
A: We supply both new (factory sealed) and tested refurbished units. Condition is clearly stated in the quotation. All units pass functional testing regardless of condition.
Q: What is the lead time for IC670ALG240?
A: Typically 3–7 business days for in-stock units. For sourced units, lead time is 2–4 weeks. Contact us for current availability.
