-4, 6, or 8 channels of quadrature encoder inputs and channel index inputs -Counts outputs from up to eight quadrature encoders -Three differential channels per encoder, including dual axis and index -Input ranges: ±25V and ±7V common mode -4.3MHz maximum clock rate -Individual software reset for each channel -Standard counting and alarm functions -Programmable for counting, speed, and direction; limit setting with interrupts -Factory flexible interrupt options The 104-QUAD-8 card is a general purpose Quadrature Encoder Counter/Interface board. It is provided in the popular 104 format and conditions and monitors the outputs of 8 encoders. I/O connectors are right-angle 34-pin headers. These functions include anything that can be programmed into the versatile LSI/CSI LS7266R1 integrated circuit. These functions include speed, direction and total count. By providing these functions, it frees the computer for higher level applications. The ability to provide an interrupt for a parameter, such as total count, further frees the computer from the necessity of constantly reading the position of an encoder. Interrupts are directed to levels #2 through #7, #10 through #12, and #15 by jumper installation. The 104-QUAD-8 card is designed for industrial applications. Each input line is buffered and capable of utilizing inputs up to 25 volts. A +5 Volt source is available for appropriate encoders. The conditioned inputs are connected to LSI/CSI LS7266R1 integrated circuits. These circuits are the heart of the card’s operation. They may be programmed for a variety of functions.
