The NI FP-PG-522 is an 8-channel pulse generator module delivering programmable digital outputs for timing, triggering, and synchronization in industrial automation and test applications. Each channel generates finite or continuous pulse trains with independently configurable pulse width, frequency, and duty cycle up to 5 kHz. The module integrates directly into National Instruments FieldPoint and Compact FieldPoint systems via keyed connectors, providing user-powered sinking outputs rated 5 to 30 VDC at 2 A per channel.
