Non-Enclosed, 5 V/TTL, 8 Bidirectional Channels, 100 ns C Series Digital Module—The sbRIO‑9401 is a configurable digital I/O interface for input or output in 4-bit increments. Therefore, the sbRIO‑9401 can create three configurations: 8 digital inputs, 8 digital outputs, or four digital inputs and four digital outputs. With reconfigurable I/O (RIO) technology (CompactRIO only), you can use the LabVIEW FPGA Module to program the sbRIO‑9401 for implementing custom, high-speed counter/timers; digital communication protocols; pulse generation; or other applications. Each channel features transient isolation between the I/O channels and the backplane. Non-enclosed modules are designed for OEM applications.
