Allen-Bradley 1746-FIO4I SLC 500 Fast Analog I/O Module

Product Overview

The Allen-Bradley 1746-FIO4I is a fast analog combination module. It is part of the SLC 500 product family. This module has two analog input channels. It also has two analog output channels. The inputs support 0-20 mA current or 0-10VDC voltage signals. The outputs support 0-20 mA current signals. This module uses a 12-bit resolution for inputs. It uses a 14-bit resolution for outputs. The conversion method is successive approximation. The input conversion time is 7.5 µs every 512 µs. The bandwidth is 7 kilohertz. This module works with SLC 500 fixed and modular controllers.

Application Scenarios

This module works well in applications with limited space. It combines input and output functions in one slot. The fast input characteristics accept signals from rapid changing variables. Use it for process control, machine control, and data acquisition. It is compatible with many other 1746 modules. Use it with 1747-L20, 1747-L30, and 1747-L40 controllers. It supports expansion I/O racks. This module is ideal for systems needing fast analog signal processing.
