National Instruments cFP-DO-403 Digital Output Module for Compact FieldPoint

The cFP-DO-403 (Part number: 777318-403) is a multipurpose Digital Output Module from National Instruments. This module is featured with 16 sinking digital output channels. Each channel is attuned with voltages from 5 to 30 VDC. This module can provide 2 amperes of current for every channel and has a maximum of 16 A squared per module. Each channel is structured with an LED, which helps indicate the channel state as on/off. The NI cFP-DO-403 module also has 2300 V transient isolation between the backplane and the output channels. The module has a hot PnP feature for setup and installation. It can also detect and identify the configuration software automatically.

The cFP-DO-403 Digital Output Module is designed to mount on a cFP-BP-x Compact FieldPoint Backplane. The backplane gives functioning power to the module. This module can be used with the cFP-CB-x Connector Block, which offers links for all 16 output channels and for an external supply. The NI cFP-DO-403 has 8 common terminals (COM). Moreover, this module has 8 power connections to power field devices (VSUP). The maximum update rate of each channel is 20 kHz. The module has an output impedance of 0.12 Ω. The NI cFP-DO-403 maximum OFF state leakage is 50 µA. The random operating vibration is 10–500 Hz; the value of sinusoidal operating vibration is the same. The operating shock value is 50 grams.

The NI cFP-DO-403 fulfills the EMC standards for electrical equipment. These standards are essential for measurement, control, and lab purposes. This module can operate at the maximum height of 2000 meters and has a pollution degree of 2. The NI cFP-DO-403 is only viable for indoor usage. The value of power consumption of this Digital Output Module is 600 mW.

The NI device weighs 4.8 oz, and measures 4.2 x 4.3 x 3.6 in. in physical dimensions. It has a recommended operating temperature range of –40 to 70 °C at ≤25 V input voltage, –40 to 50 °C at ≤30 V input voltage, a storage temperature range of –45 to 85 °C, and a non-condensing humidity range of 10 to 90% RH.
