Honeywell C7600B, H7655A Product Data

C7600B, H7655A

Solid State Humidity Sensors

PRODUCT DATA

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.

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.

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).
