Product Description

CT-3168 Voltage Analog Input Module 8AI

Module features

The CT-3168 8-channel voltage analog input module by Sichuan Odot is a high-precision industrial I/O solution engineered for global automation systems, directly addressing critical challenges like electrical noise, multi-range voltage incompatibility, and costly maintenance downtime.

It supports four standard input ranges—0–5VDC, 0–10VDC, ±5VDC, and ±10VDC—with 15-/16-bit resolution for accurate signal acquisition, even in noisy environments. Featuring a single-ended common-ground input design, it simplifies wiring, while per-channel LED indicators and configurable filter time enhance noise immunity.

Crucially, independent channel disable allows flexible I/O reconfiguration without system shutdown. Proven in European packaging machinery, Southeast Asian water treatment plants, and North American new energy test platforms, the CT-3168 integrates seamlessly with major PLC/DCS systems and complies with CE and industrial EMC standards—making it a trusted industrial analog input module for smart manufacturing, process automation, and energy monitoring.
