GE IC693ALG220 Analog Input Module – Series 90-30 PLC
Imagine a continuous process line — a chemical reactor, a water treatment plant, or a paper mill — where temperature, pressure, and flow sensors feed real-time data into the control system. Without a reliable analog input module, those critical signals become noise. Alarms go undetected. Processes drift out of spec. Unplanned shutdowns cost tens of thousands of dollars per hour. The GE IC693ALG220 is the precision interface that prevents exactly that scenario, converting raw field-level analog signals into actionable digital data for the PLC controller.
Within the GE Series 90-30 PLC ecosystem — one of the most widely deployed modular PLC platforms in North American and global industrial automation — the IC693ALG220 occupies a foundational role as a high-density analog input module. Introduced as part of GE Fanuc’s mature Series 90-30 architecture, this module continues to serve active installations across oil & gas, power generation, food & beverage, and discrete manufacturing. Its longevity in the market reflects both the robustness of its design and the scale of the installed base that depends on it for ongoing operations and MRO (Maintenance, Repair & Overhaul) procurement.

Frequently Asked Questions
Q: Is the IC693ALG220 still in production by GE?
A: The GE Series 90-30 platform has reached end-of-active-production, but Konmask.com maintains access to new-old-stock (NOS) and professionally refurbished units to support ongoing MRO requirements.
Q: Can the IC693ALG220 accept thermocouple or RTD inputs directly?
A: No. The IC693ALG220 accepts standard voltage and current analog signals. For thermocouple inputs, GE offers dedicated modules such as the IC693ALG221 (thermocouple) or IC693ALG223 (RTD). Signal conditioners can also be used to convert thermocouple/RTD outputs to 4–20 mA for use with the IC693ALG220.
Q: How many IC693ALG220 modules can I install in one Series 90-30 system?
A: The number of analog input modules is limited by the available I/O slots in your baseplate configuration and the CPU’s I/O capacity. Consult your CPU’s hardware manual for the maximum analog channel count per system.
Q: What programming software is required to configure the IC693ALG220?
A: GE Proficy Machine Edition (Logic Developer – PLC) is the current supported programming environment. Legacy systems may use Logicmaster 90-30 software for older CPU revisions.
