PRODUCT DESCRIPTION
MITSUBISHI QX423A - Digital Input Module
The MITSUBISHI QX423A is a MELSEC Q-series digital input module designed for discrete signal acquisition within industrial automation systems. This module integrates 32 channels of 24VDC binary input signals from field devices directly into the programmable logic controller's processing unit. It is engineered for rack-based PLC architectures, providing essential real-time status monitoring for manufacturing, process control, and machine automation applications.
