The NI‑9423 works with industrial logic levels and signals to connect directly to a wide array of industrial switches, transducers, and devices. Each channel is compatible with 24 V logic levels, can accept up to 30 V discrete logic levels, and has an LED that indicates the status. The NI‑9423 offers isolation between the input and output banks from channel to earth ground. The NI‑9423 is a correlated digital module, so it can perform correlated measurements, triggering, and sychronization when installed in a CompactDAQ chassis.
You can request repair, schedule calibration, or get technical support. A valid service agreement may be required.
