Operation
C7600B
The sensor provides a 2 to 10 Vdc output signal directly
proportional to the humidity of the air where the unit is
mounted.
H7665A
The sensor provides a 0 to 10 Vdc output signal directly
proportional to the humidity of the air where the unit is
mounted.
WIRING
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply before installation.
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
See Fig. 5 through 9 for wiring details. Wire input power
(16 to 40 Vdc or 16 to 30 Vac) to V+ and GND terminals.
Connect sensor output (OUT) and GND to a controller analog
input as shown in Fig. 5 through 9.
