CompactRIO Single-Board Controller Physical Channels

Last Modified: July 17, 2019

The sbRIO-9603, 9608, and 9609 controllers do not have onboard physical channels. The sbRIO-9628, 9629, and 9638 controllers have the following onboard IO characteristics.

Analog Input

Device Number of Channels Naming
sbRIO-9628, sbRIO-9629, sbRIO-9638 16 Conn0_AI/ai0 to Conn0_AI/ai15

Analog Output

Device Number of Channels Naming
sbRIO-9628, sbRIO-9629, sbRIO-9638 4 Conn0_AO/ao0 to Conn0_AO/ao3

Digital Input and Output

Device Lines Type Naming
sbRIO-9628, sbRIO-9629 4 digital input and/or output Conn0_DIO0-3/port0/line0 to Conn0_DIO0-3/port0/line3
sbRIO-9638 4 digital input and/or output Conn0_DIO0-3/port0/line0 to Conn0_DIO0-3/port0/line3
8 digital input and/or output Conn1_DIO4-11/port0/line4 to Conn1_DIO4-11/port0/line11

Conn1_DIO12-19/port0/line12 to Conn1_DIO12-19/port0/line19

Conn1_DIO20-27/port0/line20 to Conn1_DIO20-27/port0/line27

Chassis Counter Input and Output

The sbRIO-9628, 9629, and 9638 have four counters. You can use counters/timers with a C Series device using the RMC connector or with onboard I/O on models where these I/O connectors are available. The following information applies to CompactRIO Single-Board controller onboard I/O. See C Series Physical Channels for more information and counter terminal default configuration of C Series device I/O using the RMC connector.

These chassis also have a 4-bit frequency output generator, referred to as devicename/freqout, where devicename is the onboard IO module name. For example, Conn1_DIO4-11/freqout.

Each counter has four primary terminals associated with it. These are the terminals used as the SOURCE, GATE, AUX, and OUT functions. NI-DAQmx has default values for these terminals. For counter input tasks, if you know whether your signal provides the SOURCE, AUX, or GATE function and wire your signal to the default, you do not have to set the Input Terminal attribute/property.

Counter/timers are supported on the DIO 0-3, DIO 4-11, DIO 12-19 and DIO 20-27 onboard DIO devices and on parallel digital I/O modules. Refer to Digital I/O Considerations for C Series and the counter section in C Series Physical Channels for more information about C Series device specific behavior.

The following table shows the counter terminal defaults for the DIO 0-3 onboard device.
