The NI 9425 is a 32-channel, 7 µs sinking digital input C Series module for any NI CompactDAQ or CompactRIO chassis. Each channel is compatible with 12 V and 24 V levels and features 1,000 Vrms of transient overvoltage protection from channel to earth ground. The NI 9425 contains an industry-standard 37-pin D-SUB connector for low-cost cabling to a wide variety of 37-pin accessories from NI or other vendors. It works with industrial logic levels and signals to directly connect to a wide array of industrial switches, transducers, and other devices.

The NI 9425 is a serial digital module, so it cannot be used to perform counter operations when installed in an NI CompactDAQ chassis.
