Product Description

DT-3168 Analog Voltage Input Module 8AI

The DT-3168 is an 8-channel analog voltage input module from Sichuan ODOT Automation System Co., Ltd., a trusted provider of industrial I/O Solutions worldwide. It supports 0–5 VDC, 0–10 VDC, ±5 VDC, and ±10 VDC inputs with 16-bit resolution in a single-ended, common-ground configuration. Each channel features an LED indicator, configurable signal filtering, and independent enable/disable control. The module utilizes a high-speed redundant backplane bus and pluggable terminal blocks for reliable, flexible installation.
