PLCAGE: 1746-NI4  Allen-Bradley PLC Analog I/O Modules 4 inputs (±10V DC, ±20 mA) New

Features

The NI4 Analog Input module contains 4 analog input channels that are user

selectable per channel for voltage or current to support a variety of monitoring and

controlling applications.

The NI4 has 4 individual DIP switches that control the input mode of channels 0

through 3. A switch in the ON position configures the channel for current input. A

switch in the OFF position configures the channel for voltage input.
