C7600B, H7655A

Solid State Humidity Sensors

APPLICATION

C7600B, H7655A Solid State Humidity Sensors senses the

relative humidity level of an area and is used with any

controller capable of processing a 0-10 Vdc or 2-10 Vdc

signal.

FEATURES

• Long-lasting solid state sensing element is accurate

and stable over time.

• Enclosed in rugged, wall-mounted plastic case.

• Vents on top and sides of cover allow air flow to

humidity sensing element.

• Compact size and lightweight construction provide

easy mounting.

• C7600B provides 2-10 Vdc output directly proportional

to relative humidity and can be used with the H775

Humidity Controller.

• H7655A provides 0-10 Vdc output directly proportional

to relative humidity and can be used with the T7350

Temperature/Humidity Controller.

SPECIFICATIONS

IMPORTANT

The specifications given in this publication do not

include normal manufacturing tolerances. Therefore,

an individual unit may not exactly match the listed

specifications. Also, this product is tested and

calibrated under closely controlled conditions and

some minor differences in performance can be

expected if those conditions are changed.

Models: C7600B, H7655A Solid State Humidity Sensors.

Provide a dc voltage output in direct proportion to the

change in relative humidity.

Dimensions: See Fig. 1.

Case: Rugged, lightweight, compact plastic, easy to install.

Electrical Ratings:

Input: 16-40 Vdc or 16-30 Vac.

Output:

C7600B: 2-10 Vdc voltage signal; increases from 2 to 10

Vdc as humidity increases. Output voltage is directly

proportional to relative humidity increase. See Fig. 2.

H7665A: 0-10 Vdc voltage signal; increases from 0 to 10

Vdc as humidity increases. Output voltage is directly

proportional to relative humidity increase. See Fig. 3.

Maximum Power Consumption: 0.3 VA.

Mounting: Wall mount (directly to wall or standard outlet box).

Ambient Temperature Ranges:

Operating: 32°F to 125°F (0°C to 52°C).

Shipping: -40°F to +150°F (-40°C to +66°C).
