NI 9435 Screw Term, 250 VAC/DC, 3 ms, 4-Ch Sink/Source DI Module (779010-01)

±5 VDC to ±250 VDC/10 VAC to 250 VAC, 4-Channel (Sinking/Sourcing Input), 3 ms C Series Digital Module
The NI‑9435 works with industrial logic levels and signals to connect directly to a wide array of industrial switches, transducers, and devices. Each channel accepts signals from ±5 VDC to ±250 VDC and 10 VAC to 250 VAC; features transient overvoltage protection between the input channels and earth ground; and has an LED that indicates the status. The NI‑9435 is a correlated digital module, so it can perform correlated operations, triggering, and synchronization when installed in a CompactDAQ chassis.
