Configuring Your Module
The NI4, NIO4I, NIO4V, FIO4I, and FIO4V analog modules have user-selectable
DIP switch settings, which allow you to configure the input channels as either
current or voltage inputs. The switches are located on the analog module board.
The following illustration shows the ON and OFF switch settings. Switch orientation
is also provided on the nameplate of the module.
Switch Settings for the 1746-NI4
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.
ATTENTION
Care should be taken to avoid connecting a voltage source
without a current transmitter, etc. to a channel configured for
current input. Improper module operation or damage to the
module can occur.
ON - Configures channel for current input
OFF - Configures channel for voltage input
Switch 1 = Channel 0
Switch 2 = Channel 1
Switch 3 = Channel 2
Switch 4 = Channel 3
