Input Signal
The C7232 Sensors have an adjustable range. These ranges
are determined by the SW1 and SW2 jumper settings (see
Table 2).

When the level reaches this value, the contacts close; when
the level drops 100 ppm below this value, the contacts open.

Output Signal
The output signal can be adjusted for 0/2-10Vdc or 0/4-20mA
(see Table 3).
Example
For a CO
setting of 0-2000 ppm and a voltage output of 0-10 Vdc, the output would be as shown in Table 4 (arbitrary points

along the analog curve).

NOTES:
—
On duct models, remove the screw holding the
M17543
board in place to view jumper settings on reverse.
(See Fig. 7.)

The CO
are independent of each other. 0-100% and
20-100% are simply markings for the OUT jumper
settings on the sensor (to differentiate between
the two voltage and the two current ranges) and
do not refer to or alter the ppm range chosen.
