Simpson Hawk 3 User Manual

The 0-10VDC output card will generate an isolated output between 0VDC and
10VDC that is related to the input level. This relationship can be set using the
menu.
Linearization will also affect the relation. The factory default is when the input
is at its lowest level the output is 0VDC. When the input is at the maximum
rated input the output is at 10VDC.
The Excitation output card provides a factory set isolated DC voltage of either 12VDC or 24VDC. The
maximum output current for the 12VDC is 30mA and 20mA for the 24VDC. Excitation is available alone
or can be included with the other outputs.
4.1 Excitation
The RS-485 card is used for communication in a network where multiple
sensors (not necessarily those of Hawk 3) report back to a central host
computer.
, half
duplex serial communication, and will respond on a polled basis only. Each
Hawk 3 will respond to it’s own unique address only after being requested by
the host. The Hawk 3 remains a listener until asked to respond. (See section
7 of this manual for further details about using the RS-485 card.)
