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. The input adapter has a plug-in modular connector that
allows it to be added easily to a HOBO station.

* 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.

Mounting

Use the self-adhesive hook-and-loop tape included in the package to mount the input adapter
inside the logger enclosure. To mount more than one adapter, use the back of the logger
enclosure door.
For the HOBO Micro Station, you can place the input adapter inside the logger enclosure and
allow it to float freely. It is not necessary to use the hook-and-loop tape.

Mounting Considerations

• If sensor cables are left on the ground, use a conduit to protect against animals, lawn
mowers, exposure to chemicals, etc.
• Refer to the logger manual for additional details on mounting.
