HOBO - Contact Closure Pulse Input Adaptors

The Contact Closure Pulse Input Adaptor connects sensors with pulse outputs to loggers with smart-sensor inputs. This smart sensor is compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second), and a preferred switch-type of normally-open

Easy to add to HOBO loggers and stations

The Contact Closure Pulse Input Adaptor connects sensors with pulse outputs to loggers with smart-sensor inputs. This smart sensor is compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second), and a preferred switch-type of normally-open

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® loggers and stations. The adapter has a plug-in modular connector that allows it to be added easily to these devices. 


Features

  • Plug-n-play adapter for pulse output sensors
  • Automatically recognized by H21, H22, U30, and ZW data loggers
  • Compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second)

CE The CE Marking identifies this product as complying with all relevant
directives in the European Union (EU).
* 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.
** A single HOBO station can accommodate 15 data channels and up to 100 m (328 ft) of smart sensor cable (the digital
communications portion of the sensor cables).
