Sub Category: Humidity Controls
System 350TM W351P Electronic Proportional Plus Integral Humidity Control
The W351P control is an electronic, proportional plus
integral humidity control with analog 0-10 VDC and
0-20 mA outputs. The W351P control has three
user-selectable integration constants, a wide setpoint
range of 10-90% RH, and an adjustable throttling
range of 2-20% RH.
The W351P control is designed to work with an
HE-67S3-0N0BT Room Sensor Humidity Transmitter
or HE-67S3-0N00P Duct Sensor Humidity Transmitter.
Like all System 350 products, the W351P control
housing is a NEMA 1, high-impact plastic enclosure.
The modular design provides easy, plug-together
connections for quick installation and future
expandability.
Features and Benefits
❑ Modular Design Provides the flexibility to add up to four S351 Stage Modules, a
D351 Humidity Display Module, and a Y350R Power Module
❑ Plug-together Connectors and
35 mm DIN Rail Mounting
Eliminates wiring between modules and reduces installation costs
❑ Adjustable Setpoint Range of
10-90% RH
Reduces inventory by covering the humidity range required to
support most humidity applications
❑ Adjustable Minimum Output Signal Allows the user to adjust the minimum output between 0-60% of
the output signal voltage; can also be used to set minimum valve
position
❑ Adjustable Throttling
Range of 2-20% RH
Enables user to match the amount of control (maximum to
minimum) to application requirements
❑ Humidification or Dehumidification
Modes of Operation
Works in a variety of humidification or dehumidification
applications
❑ Three Selectable Integration
Constants
Allows user to adjust system recovery rate to setpoint humidity at
Slow, Medium, or Fast to meet application requirements
❑ Interchangeable Humidity
Transmitters
Increases versatility and serviceability
