C Series User Interface Module

4-Channel C Series User Interface Module—The NI‑9344 is a user-programmable switch and LED module that you can use to interact quickly with a CompactDAQ or CompactRIO system. Each switch acts as a manual digital input channel for debugging code, starting and stopping processes, or clearing errors. Each LED is powered by a digital output channel, and you can individually program each LED to provide both status and diagnostic updates. The NI‑9344 is ideal for prototyping or deployment environments.
