National Instruments 777318-600 Digital Output Module for Compact FieldPoint

Part Number 777318-600 is the identifying part number for the National Instruments cFP-DO-403 Digital Output Module for Compact FieldPoint. 

The 777318-600 features 16 sinking digital output channels having a range of 5 to 30 VDC and a maximum update rate of 20 KHz. Likewise, it has 8 common terminals (COM) and 8 power connections to power field devices (Vsup). The output impedance is 0.12 Ω (equating to 0.12 V drop at 1 A). Likewise, the maximum current per channel is 2 A while it is 16 A2 for all channels. Furthermore, the maximum OFF state leakage is 50 μA while the output delay time is 50 μs. The module draws 600 mW of power from the network module. The channel-to-ground isolation is 250 Vrms while there is no channel-to-channel isolation. 

The 777318-600 weighs 110 g and features green POWER and READY indicators as well as 16 green output state indicators. The POWER LED lights up when the module is inserted into a terminal base or a backplane and power is applied to the connected network module. Similarly, when the network module recognizes the presence of the output module and sends in the initial configuration, the READY indicator lights up. Furthermore, each channel has a green, numbered output state indicator that lights up when the channel is in the ON state.  

The recommended temperature range for the operation of the 777318-600 is dependent on the input voltage: -40 to 70 °C for input voltage ≤25 V and –40 to 50 °C for input voltages ≤30 V. at a relative humidity of up to 10% to 90% RH. Likewise, the device is only meant to be used indoors within a maximum altitude of 2000m (must be mounted inside a sealed enclosure for outdoor use). On the other hand, it can be stored at –45 to 85 °C. The device meets the following safety standards for electrical equipment for measurement, control, and laboratory use:  EN 61010-1, IEC 61010-1, UL 61010-1, and CAN/CSA-C22.2 No. 61010-1.
