Pulse Input Adapters (Part # S-UCC/D-M006)

for use with HOBO

The Pulse Input Adapters are used to log the number of switch

closures per interval and are designed to work with smart

sensor-compatible HOBO data loggers. The adapter has a

plug-in modular connector that allows it to be added easily to

these loggers. Two versions are available: one for mechanical

contact closures (ideal for connecting tipping-bucket rain

gauges to HOBO H21 series loggers), and one for solid-state

electronic switches (used for connecting compatible pulse

output sensors to HOBO H22 series loggers).

For maximum battery life, the Pulse Input Adapters should be used with their preferred switch type. The adapters

will work with active high inputs (S-UCC) and normally closed switches (S-UCD), but battery life will not be

optimized.

Be sure to follow the instructions included with the logger to ensure that the logger is properly sealed where the sensor cable exits the logger enclosure.

Page 5 Pulse Input Adapters Connecting to the Logger To start using the Pulse Input Adapter, stop the logger and insert the adapter’s modular jack into an available sensor connection port on the logger. If no port is available, use a 1-to-2 sensor connection adapter (Onset Part # S-ADAPT-5), which allows you to plug two sensors into one port on the HOBO Energy Logger Pro.
