+\- 1% at 70° F
Approx. 1 V / 175 FC
*Connect the red wire to either the +12VDC or +5VDC terminal.
The +12V terminal is preferred because of the higher resolution it
provides. Note that on MultiFlex boards manufactured before April
2004 you must use the +5VDC terminal.
The dip switch for the 16AI input should be set to the
OFF position.
The sensor connections to the input point on the 16AI
board are not polarity sensitive. The sensor can be
wired to any available point on the 16AI board and is
connected as shown in the Sensor Wiring
1. Connect red and yellow lead to the SIG input
2. Connect green to the 0V input
3. Connect black to the +12V input
NOTE: The sensor does not follow the standard
control wiring color code. The sensor must
be wired as shown in the diagram.
