National Instruments 777318-403 Digital Output Module .

The part number 777318-403 from National Instruments is the identifying part number for the cFP-DO-403 Digital Output Module. This module is an sinking digital output module with 16 output channel requiring 5 to 30 VDC, capable of providing up to 2 A per channel that makes it suitable for high loads applications such as relays, solenoids and indicator lights. The output channel of the module has an impedance of  0.12 ohms which can be increased to 2.0 ohms to help limit current, manage power dissipation, and provide better protection against short-circuiting by reducing fault currents. The 777318-403 module offers a high isolation voltage of 2,300 V rms with no isolation between channels, thus with this, it can protect the module from potential damage and even makes it suitable for industrial environments where noise and transient can pose risks to reliability and efficiency of the module.

The digital output module has compact design with dimensions of 10.7 cm by 10.9 cm by 9.1 cm (4.2 by 4.3 by 3.6 in.) and weighs 136 g making it lightweight. This module is designed to operate at an ambient temperature of -40 to 70 degrees Celsius and storage temperature of -55 to 85 degrees Celsius with a relative humidity level ranging from 10% to 90%, noncondensing. 

This module is built to endure harsh conditions, with an operating vibration of 10 to 500 Hz, 5 g rms that is random under (IEC 60068-2-64) standards and 10 to 500 Hz, 5 g that is sinusoidal under (IEC 60068-2-6) standards, with operating shocks of 50 g, 3 ms half sine, 18 shocks at 6 orientations, 30 g, 11 ms half sine, 18 shocks at 6 orientations, under (IEC 60068-2-27) standards.

The 777318-403 also features flyback diode as protective feature that protects the module from high voltage spikes and reduce electromagnetic interference in the circuit. with this feature, it leads to a longer lifespan for the module and improves systems reliability. This model is made under IEC 61010-1, EN 61010-1, UL 61010-1, CSA 61010-1 standards with electromagnetic Compatibility (EMC) Standards as well ensuring both operational safety and reliability.
