The National Instruments FP-DO-400 module features eight sourcing digital output channels. Each channel is compatible with voltages from 5 to 30 VDC and can source up to 2 A per channel with a maximum of 9 A squared per module. （The sum of the squares of the output currents from all eight channels must be no greater than 9.） Each channel has an LED to indicate the channel on/off state. The module features 2300 V transient isolation between the output channels and the backplane. To make installation and setup easier the NI FP-DO-400 features HotPnP （plug and play） operation and is automatically detected and identified by the configuration software. 5 to 30 VDC range HotPnP （plug and play） operation -40 to 70 °C operating range LED on/off state indicator, per channel Up to 2 A per channel, 9 A squared per module
