产品介绍
The Allen-Bradley 1746-NI16V is a high-density analog input module designed for the SLC 500 programmable controller system. It provides precise acquisition / voltage-based analog signals and converts them into digital data for processing within the PLC, making it suitable for applications requiring accurate measurement and control.
This module supports 16 single-ended analog input channels, allowing efficient integration / multiple field signals within a compact footprint. It is specifically designed for ±10V DC input ranges, making it ideal for interfacing with transmitters, sensors, and instrumentation devices that output voltage signals.
A key feature / the 1746-NI16V is its s/tware configurability, enabling flexible channel configuration and scaling directly through the PLC program. This reduces the need for external signal conditioning and enhances system adaptability. The module is widely used in industrial automation systems where high channel density and reliable analog performance are required.
