GE IC697MDL671 Discrete Input Module

Product Introduction

The GE IC697MDL652 Discrete Input Module is an interrupt-capable input module designed for the GE Fanuc Series 90-70 PLC system. This specialized module provides 14 discrete interrupt input points, each operating at 24V DC, and supports both positive and negative logic. It is divided into four isolated groups of four points each, allowing enhanced electrical isolation, robust noise immunity, and reliable operation in industrial environments.

The module is engineered for applications where fast and prioritized signal detection is critical. The interrupt functionality enables the CPU to respond immediately to high-priority events, such as emergency stop signals, critical sensor feedback, or machine protection inputs. Each of the 14 interrupt-capable points can be configured independently to trigger specific interrupt routines in the PLC program, making this module ideal for high-reliability control and automation applications.

The IC697MDL652 integrates seamlessly into existing Series 90-70 racks, supporting multiple interrupt modules in a single system for scalable control architectures. Its design ensures easy installation, real-time diagnostics, and long-term reliability under continuous industrial use.
