Each channel has a DIO pin to which you can connect a digital input or output device. The 32 DIO channels are internally referenced to COM, so you can use any of the four COM lines as a reference for the external signal.

You can independently configure each DIO channel in software for input or output. The DIO channels have Schmitt trigger inputs and are compatible with 5 V TTL logic devices. Each input channel has hysteresis for improved performance with noisy and non-monotonic input signals. Each channel also has a pull-down resistor and includes overvoltage, overcurrent, and short-circuit protection. Refer to the Specifications section for more information about input thresholds and overvoltage protection. Refer to the

Overcurrent/Short-Circuit Protection section for more

information about overcurrent and short-circuit protection.

Refer to Figure 3 for an illustration of several types of digital devices connected to the NI 9403E.

Overcurrent/Short-Circuit Protection

The overcurrent protection allows only a specified amount of current through the output channels to protect the NI 9403E from short circuits. If the NI 9403E goes into an overcurrent state, the module sets all the DIO channels to high impedance for approximately 280 milliseconds. When the channels are in this state, the NI 9403E can accept new line direction configuration and output state data but cannot pass valid input data to the software. After the protection period, the NI 9403E automatically recovers to the latest direction configuration and output state. If the overcurrent condition still exists, the module again sets the channels to high impedance. This cycle continues until the overcurrent condition is removed. Refer to the Specifications section for more information about the maximum output current.

Sleep Mode

This module supports a low-power sleep mode. Support for sleep mode at the system level depends on the chassis that the module is plugged into. Refer to the chassis manual for information about support for sleep mode. If the chassis supports sleep mode, refer to the software help for information about enabling sleep mode. Visit

ni.com/info and enter cseriesdoc for information about

C Series documentation.

Typically, when a system is in sleep mode, you cannot communicate with the modules. In sleep mode, the system consumes minimal power and may dissipate less heat than it does in normal mode. Refer to the Specifications section for more information about power consumption and thermal dissipation.
