National Instruments 777318-401 Digital Output Module

The part number 777318-401 from National Instruments is the identifying part number for the cFP-DO-401 Digital Output Module. This output module features 16-channel sourcing digital outputs with a switching voltage ranging from 5 Volts to 30 Volts DC allowing this module to control various types of devices. This module can output 1.5 Amperes of current per channel allowing it to drive load using high current directly. With 16 output terminals 

At 10 to 30 Volts, this module has an output impedance of 0.3 ohms ensuring minimal voltage drops across the output channels allowing the module to maintain efficiency and the overall quality of the signal. For the output to turn ON, there is a delay of 20 μs, while the delay for it to turn OFF is 50 μs providing fast response time, especially for time-critical control applications.

The 777318-401 draws power for the Compact FieldPoint backplane consuming approximately 600 mW of power. To protect the cFP system and controller from high voltage levels and transient overvoltage conditions, the 777318-401 features a 2,300 Vrms optical isolation bank. The module is equipped with flyback diodes to protect against inductive loads, preventing voltage spikes that can damage the module or connected devices. It also provides overcurrent protection by setting the module to an OFF state during startup preventing the module or connected devices from drawing excess current. 

The 777318-401 has an operating temperature range of -40 degrees Celsius to 70 degrees Celsius and a storage temperature range of -55 degrees Celsius to 85 degrees Celsius. The module can withstand relative humidity levels from 10% to 90%, is non-condensing, and is rated for a maximum altitude of 2,000 meters. It meets IEC 60068-2-64 and IEC 60068-2-6 standards for vibration and IEC 60068-2-27 standards for shock. The module also complies with various international safety and electromagnetic compatibility (EMC) standards, including IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1 for safety, and EN 61326, EN 55011, and FCC Part 15 Class A for EMC making this module great for highly challenging industrial environments and providing high quality standard.
