PLCAGE: 1746-NO4I  Allen-Bradley PLC 1746 Analog Output Modules 4 outputs (0-20 mA) New

Features

The NO4I and NO4V Analog Output Modules provide 4 analog output channels.

The NO4I module contains 4 current outputs.

The NO4I and NO4V analog output modules have an external 24V dc power

switch, SW1, which gives you the option of using an external power supply. In the

UP position, power is drawn from an external power source. In the DOWN

position, power is drawn from the backplane of the module. The switch is located

on the analog module board. Switch orientation is also provided on the nameplate

of the module.
