Product Introduction
The GE IC693MDL643 is a 24VDC Positive Logic Input Module, designed for use with the GE Fanuc Series 90-30 PLC system. This industrial-grade module provides 16 discrete input points, grouped into four isolated groups of four inputs each. The module is specifically built to detect the presence of 24VDC voltage levels as ON signals, using positive logic, which means the module recognizes a high-level DC signal (typically >11V) as an active input.
Engineered for high reliability in demanding industrial environments, this input module is ideal for connecting a wide range of field devices like push buttons, limit switches, and other binary sensors. It is mounted in the I/O slot of a Series 90-30 baseplate and communicates seamlessly with the CPU via the system’s backplane.
The IC693MDL643 is a cost-effective and efficient choice for integrating discrete input monitoring into your automation solution, offering galvanic isolation, fast response time, and robust signal detection.
