Digital Input Module 32DI 24VDC Sink or Source

CT-124H Digital Input Module 32DI 24VDC Sink or Source Type The CT-124H is a versatile 32-channel digital input module from Sichuan ODOT Automation System Co., Ltd., supporting both sink (PNP, high-level valid) and source (NPN, low-level valid) wiring with 24VDC inputs via a 34-pin male connector. It interfaces with dry contacts, active outputs, and 2-/3-wire digital sensors. Each channel features optocoupler isolation between field inputs and the internal bus, configurable signal filtering, and adjustable input holding time.  With counting enabled via ODOT configuration software and an optional sub-module, every channel provides an independent 32-bit counter (counting frequency <200 Hz), with user-defined counting mode, direction, and byte transmission sequence—ideal for high-density, flexible industrial I/O applications.   Technical Parameters General parameters Power Max.60mA @ 5.0Vdc Isolation I/O to internal bus: opto-couple isolation (3KVrms) Field Power Nominal:24V…
