LLAC4 Four-Channel, Low-Level
AC Conversion Module
1. General Description
The LLAC4 is a peripheral device used to increase the number of low-level AC
signals a datalogger can monitor. The module enables four datalogger control
ports to emulate pulse-counting channels by converting the low-level AC signals
to the logic levels datalogger control ports require.
The LLAC4 is often used to measure up to four anemometers, and is especially
useful for wind profiling applications. Compatible wind sensors include, but are
not limited to, the 05103 Wind Monitor, 05106 Wind Monitor-MA, 05305 Wind
Monitor-AQ, 03001 Wind Sentry Set, and 03101 Wind Sentry Anemometer.
