OPTIONAL ISOLATED 4-20MA OUTPUT BOARD
The optional 10-0250 Isolated 4-20mA output board provides two 4-20mA outputs that are electrically
isolated from sensor inputs and the 24 VDC power source. Each 4-20mA output shares the same common
ground and are
therefore not isolated from each other
. This board is
connected “piggyback”
to the back
of the GASMAX II Display Assembly. GASMAX II units may be field upgraded with this option at any time.
NOTE
: THE ISOLATED 4-20MA AND MODBUS / RELAY BOARDS SHARE THE SAME CONNECTOR AND
THEREFORE CANNOT BE INSTALLED AT THE SAME TIME.
