The NI 9411 is a 6-channel, ±5 V to 24 V, 1 ¼s, single-ended TTL or differential digital input module designed for use with CompactDAQ and CompactRIO systems. It provides six digital input channels that support both single-ended and differential signal types, making it suitable for interfacing with a variety of industrial digital sensors and encoders. The module features a 1 ¼s timestamp resolution, allowing for precise measurement of high-speed digital signals. The NI 9411 is engineered for robust performance in demanding environments, with isolation between the input channels and the backplane to protect against ground loops and electrical noise. It is hot-swappable and supports direct connection to industrial devices, making it ideal for applications such as position and velocity measurement, event counting, and digital signal monitoring in automation and test systems.
