Analog Output option board
This provides two analog outputs (4-20mA and 0-10V) that follow the reading on the
display (see page 13).
The output can be programmed to any range, by setting the Analog Output Offset and
Analog Output Full Scale parameters.
When the display reading is equal to the Analog Output Offset value, the outputs will be
4mA and 0V.
When the display reading is equal to the Analog Output Full Scale value, the outputs will
be 20mA and 10V.
When the display reading is in between these two values, the outputs will be:
V
=
(Display Reading - Output Offset) x 10
(Output Full Scale - Output Offset)
(
I
=
(Display Reading - Output Offset) x 16
(Output Full Scale - Output Offset)
RS485 option board
This provides a two-way serial communication link with a remote computer (see page 13).
The serial link can be programmed by setting the RS485 Serial Address, RS485 Baud
Rate and RS485 Parity parameters.
For further information about the serial communication protocol, contact your local
Trumeter office.
