Product Description
The GE IC693MDL646C is a high-density 32-point discrete DC input module engineered for the GE Series 90-30 Programmable Logic Controller (PLC) system. It accepts 24V DC input signals using positive logic, offering a reliable interface for field input devices such as limit switches, pushbuttons, and proximity sensors.
This module is ideal for applications requiring a large number of input channels while conserving space. Its compact form factor, integrated LED status indicators, and robust electrical isolation make it a preferred choice in demanding industrial control environments. It features a dual 24-pin connector design and supports connection via GE’s Terminal Block Quick Connect (TBQC) system or user-supplied terminal strips.
