Laurel Electronics Laureate™ L5/L6/L7/L8 Multifunction Counter/Timer/Rate Meter
The Laurel Electronics Laureate™ dual-channel frequency, rate and period meter is a basic operating mode of the Laureate™ counter with the FR signal conditioner board. It can display frequency from 0.005 Hz to 1 MHz, rate in engineering units, and period (inverse of frequency). The normal displayed value can range up to 999,999 counts. Each channel (A or B) may be independently scaled for frequency, rate or period. The displayed channel is selected via a front panel push button. Examples of applications are the accurate display of AC line frequency, RPM, speed from proximity switch inputs, and flow from turbine flow meter inputs.
The FR dual-channel signal conditioner accepts inputs from proximity switches with a PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, low-level outputs from turbine flow meters down to 12 mV, and high-level AC line inputs up to 250 Vac. A built-in isolated 5, 10, or 24 DCV excitation supply can power proximity switches and other sensors, thus eliminating the need for an external power supply.
An "Extended" counter version (models L7 and L8) provides all capabilities of the standard counter plus the following: rate and total simultaneously, custom curve linearization and arithmetic functions.

- Optional Extended Counter: all capabilities of Standard counter, plus
- Rate and total simultaneously
- Custom curve linearization
- Arithmetic functions A+B, A-B, AxB, A/B, A/B-1 (draw)
