GE Fanuc IC693MDL340 Product Documentation
1. Product Description
The GE Fanuc IC693MDL340 is a 4-channel analog input module designed for GE Fanuc’s 90-30 series PLC systems. It converts analog signals from sensors (e.g., thermocouples, RTDs, voltage/current transmitters) into digital data for PLC processing. The IC693MDL340 supports voltage (0–10V DC) and current (4–20mA) inputs, with 12-bit resolution and galvanic isolation to protect against electrical noise. Its modular design and plug-and-play compatibility make it ideal for industrial automation, process control, and monitoring applications.
