An adaptor to connect to compatible data loggers

The 12-Bit 4–20 mA Input Adapter is used for sensors with 4–20 mA current loop outputs and is designed to work with the HOBO® stations. The input adapter features both a battery-saving switched input and a non-switched input. It also provides a trigger source voltage for controlling power to external sensors, while offering digital filtering that improves measurement accuracy with 32 readings/sample and 60 Hz noise rejection. The input adapter has a plug-in modular connector that allows it to be added easily to a HOBO station.


Features

  • 12-bit resolution
  • Digital filtering improves measurement accuracy with 32 readings/sample; 4-20 mA adapter has 60 Hz noise rejection
  • Measurement averaging over logging interval further enhances accuracy
  • Plug-in modular connector for easy interface with HOBO stations
  • Screw terminal for connecting to sensors
  • HOBO RX3000 and U30 stations have room for two adapters
  • Use with HOBO USB Micro Station and HOBO MicroRX Station requires Smart Sensor Consolidator Box (S-ADAPT-6) and an extension cable
  • Represents one data input channel

* The input adapter can provide readings as low as 0 mA. This can be helpful when diagnosing sensor issues such as open inputs.
** A single 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), although available space in the enclosure may limit the number of sensors you can attach.
