The OptiLogic OL2258 High Speed Pulse Counter module provides for direct pulse

counting for a variety of high speed pulse interface applications. Typical applications include
motion control, metering and velocity measurement. The OL2258 contains on board intelligence
necessary for processing and counting pulse information as well as automatically triggering control
outputs.

The OL2258 can be configured configured to operate in one of three pulse counting modes.

These modes are 1) Pulse & Direction, 2)Up/Down Count and 3) Quadrature . Pulse & Direction
and Up/Down count will operate at up to 80KHz input pulse rates. Quadrature inputs count each
quadrature state transitions at up to 160 KHz. Additionally, the OL2258 will return frequency
information.
