National Instruments 783907-01 Digital Output Module

The part number 783907-01 from National Instruments is the identifying part number for the NI-9472 Digital Output Module. This module features 8 sourcing-type digital output channels optically isolated for protection. Each channel of this module can provide a current of 0.75 Amperes when operating with an external voltage supply of 6 to 30 volts DC. The output channel of the module has an impedance of 0.07 ohms which can be increased to 0.13 ohms to help limit current, manage power dissipation, and provide better protection against short-circuiting by reducing fault currents.

This module has an isolation voltage of 30 Volts DC maximum between channel and ground connections, while the channel-to-earth connections can withstand a maximum voltage of 2300 Vrms. When considering the DSUB configuration of the 783907-01 Digital Output Module users can expect a reduced isolation voltage rating between channel to earth with a continuous voltage rating of 60 volts DC and can withstand 1000 Vrms. If the output channels of the module exceed a maximum current of 14 Amperes the module can trip and shutdown within 14 μs to protect the internal circuitry. 

The 783907-01 consumes 230 mW maximum when connected to its compatible chassis when in active mode and 0.4 mW when in sleep mode making the device efficient. This module can dissipate 1.5 Watts of power when operating in active mode and 55 mW when in sleep mode. 

This module should only be operated in an environment with a maximum temperature range between -40 degrees Celsius and 70 degrees Celsius making this module excellent for environments with extreme temperatures. Environments with high humidity around 90% or less are excellent for operating this module. It also features an IP 40 protection rating protecting solid objects and scratches but not water or moisture. The has a width of 2.78 inches and a length of 3.47 inches, and it weighs only 139 grams- making it compact and portable.
