Introduction
The GE Fanuc IC693MDL748 Positive/Negative Logic Output Module is a rugged and versatile digital output interface designed for the Series 90‑30 programmable logic controller (PLC) platform. It enables the PLC to control external field devices by delivering discrete output signals that represent either positive or negative logic states.
This output module supports flexible control configurations, making it ideal for applications where both sourcing (positive logic) and sinking (negative logic) output behavior is required. Its industrial‑strength design ensures reliable switching performance in electrically noisy environments, helping deliver consistent automation control for manufacturing and process systems.
