The NI PC-LPM-16/PnP is a multifunction I/O board for data acquisition and control applications on ISA-based systems. This Plug and Play enabled device delivers 16 channels of 12-bit analog input, 16 lines of TTL-compatible digital I/O (8 input, 8 output), and 2 channels of 16-bit counter/timer functionality. Designed for low power consumption and compact form factor, the PC-LPM-16/PnP interfaces with legacy PC platforms including IBM PC/XT, PC AT, and PS/2 systems, while supporting laptop-compatible computers.
