25 kS/s/ch synchronous, ±10 V, 16-channel C-Series voltage output module – The NI-9264 is a synchronous updated analog output module to meet the needs of higher channel number systems. Higher density modules save chassis space, leaving room for other measurement types. Each channel has a digital to analog converter. The NI-9264 with spring terminals uses 36-hole connectors to connect the output channels, each with a ground connection.
