Description
The SNAP-AIRATE module provides two channels of
frequency-to-digital conversion. The nominal input range is 0
to 25,000 Hz with an over-range capability to 27,500 Hz. Nine
volts through a 4.7 K ohm pull-up resistor are provided
internally for use with devices that have open collector
outputs. This feature eliminates the need for the user to
provide the pull-up voltage supply and associated wiring,
barrier strips, etc.
The module works with TTL, CMOS, and open collector
outputs. Truly a two-wire hookup, the SNAP-AIRATE module is
ideally suited for use with a tachometer.
