GE IC697MDL671 Interrupt Input Module – Series 90-70 Programmable Controller
In high-speed industrial automation environments, a missed interrupt signal can cascade into unplanned downtime, damaged tooling, or even safety incidents. When a conveyor jam, emergency stop, or high-priority sensor event demands immediate CPU attention, a standard polling-based input module simply cannot respond fast enough. The GE IC697MDL671 Interrupt Input Module was engineered precisely for these mission-critical moments — delivering hardware-level interrupt capability that bypasses the normal I/O scan cycle and forces the CPU to respond within microseconds.
The IC697MDL671 occupies a specialized position within GE’s Series 90-70 modular PLC platform — one of the most widely deployed large-scale automation architectures in North American and global process industries. As a discrete interrupt input module, it enables event-driven programming that is essential for applications where deterministic response time is non-negotiable. Its continued demand in the global industrial automation market reflects the long operational lifespan of Series 90-70 installations across power generation, oil & gas, automotive, and heavy manufacturing sectors.

Frequently Asked Questions
Q: What is the difference between the IC697MDL671 and a standard discrete input module?
A: A standard discrete input module is polled during the CPU scan cycle. The IC697MDL671 generates a hardware interrupt, forcing the CPU to immediately execute an interrupt service routine (ISR) upon input state change — critical for time-sensitive events that cannot wait for the next scan.
Q: Is the IC697MDL671 still in production?
A: GE (now part of Emerson / GE Vernova ecosystem for automation) has transitioned away from the Series 90-70 platform. The IC697MDL671 is available as new-surplus or refurbished stock. Konmask.com maintains inventory to support ongoing plant operations.
Q: Can I use this module with a Series 90-30 or PACSystems rack?
A: No. The IC697MDL671 is exclusively compatible with Series 90-70 racks. It is not interchangeable with Series 90-30 (IC693 prefix) or PACSystems RX7i/RX3i hardware without a rack adapter — consult GE documentation for migration paths.
Q: What warranty do you offer?
A: We offer a standard 90-day functional warranty on all modules. Extended warranty options are available — contact us for details.
Q: Do you provide a certificate of conformance or test report?
A: Yes, upon request we can provide inspection records and, where available, functional test documentation for the specific unit shipped.
