13556-E MAN-ZW-005
The HOBO ZW-005 data node is configured with a temperature/RH channel designed to accept
the included temperature/RH cable, along with one analog and one pulse channel. The analog
channel accepts a wide range of Onset and third-party sensors/transducers with 0–2.5 VDC
output, including temperature and AC current sensors. Specifications for Onset sensors are
available at onsetcomp.com or from an Onset Authorized Dealer. For 0–5 VDC, 0–10 VDC, or
4–20 mA output, use optional Onset part numbers CABLE-ADAP5, CABLE-ADAP10, or CABLE 4-
20 mA respectively. CABLE-2.5-STEREO is required to connect to the pulse channel (connect the
pulse output device to the cable's black and white leads).
This node has routing capability in the ZW wireless network when initially powered with an AC
adapter. Refer to the HOBO ZW Series Wireless Network Quick Start Guide for information on
how to set up this node.
