Product Introduction
The GE IC697MDL650 Discrete Input Module is a high-density, high-performance input module designed for the GE Fanuc Series 90-70 PLC system. It provides 32 input points for 24V DC signals using positive logic, allowing the module to detect “ON” status when a high-level DC voltage is applied.
This module is engineered to deliver robust and reliable signal acquisition in demanding industrial environments. It is ideal for applications requiring large numbers of discrete input channels while maintaining strong electrical isolation and noise immunity. Each input is optically isolated from the backplane and from each other in grouped configurations to ensure maximum system reliability and fault tolerance.
The IC697MDL650 integrates seamlessly with GE 90-70 series racks, CPUs, and communication modules, offering consistent performance across large-scale automation systems. Its rugged design and wide environmental tolerance make it suitable for continuous operation in harsh industrial conditions.
