CT-124D Digital Input Module32DI 24VDC Sink or Source

The CT-124D is a rugged 32-channel digital input module engineered for Industrial Automation, delivering reliable signal acquisition in demanding environments. Supporting 24VDC sink/source wiring, this PLC digital input module seamlessly interfaces with PNP/NPN sensors, dry contacts, and active output devices—making it one of the most versatile industrial I/O modules on the market.

Built with optocoupler-isolated DI architecture, it provides exceptional high-noise immunity, effectively shielding the internal bus from field-side electrical disturbances—a critical advantage for applications prone to signal drift or false triggering.

Each of the 32 inputs features configurable digital signal input filtering time, signal hold function, and independent settings for counting mode and direction. When paired with the optional counting submodule, the CT-124D becomes a powerful digital module with counter function, offering a 32-bit counter per channel (counting frequency < 200Hz) for precise pulse counting, speed monitoring, and event tracking.

Designed for DIN-rail mounting and built to industrial standards, this 24VDC digital I/O module is widely deployed in packaging machinery, automated logistics sorting systems, automotive manufacturing lines, and smart warehousing—where accuracy, durability, and real-time data integrity are non-negotiable. As a core component of modern control architectures, the CT-124D empowers engineers to build scalable, future-ready industrial automation I/O Solutions with confidence.
