Production Specification

The SNAP-AIRATE provides two channels of frequency-to-digital conversion at 0-25,000 Hz. Nine volts through a 4.7 K Ohm pull-up resistor are provided internally for use with devices that have open collector outputs. The module works with TTL, CMOS, and open collector outputs and is ideally suited for use with a tachometer.

Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley Logix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.
