System 350TM P352PN Electronic Proportional Plus
Integral Pressure Controls for PSI Applications

The P352PN Series controls are electronic proportional plus integral or proportional-only pressure controls that generate a 0 to 10 VDC and a 0 to 20 mA analog output signal based on sensed pressure. Three models are available with setpoint ranges of 0-100 psi, 90-250 psi, and 240-600 psi. The P352PN Series controls have a wide adjustable throttling range (proportional band), as well as three selectable integration constants. The P352PN Series controls are housed in a NEMA 1 high-impact thermoplastic enclosure. The modular design provides easy, plug-together connections for quick installation and integration with specified power, stage, and display modules.

Features and Benefits
❑ Modular Design Provides the flexibility to add a D352 Pressure Display Module, S352 Stage Modules, and a Y350R Power Module
❑ Plug-together Connectors and 35 mm DIN Rail Mounting Eliminates wiring between modules and reduces installation costs
❑ Three Models Cover Wide Setpoint Ranges: 0-100 psi, 90-250 psi, and 240-600 psi Reduces inventory while providing control for most positive-pressure refrigeration and HVAC applications, in three overlapping pressure ranges
❑ Adjustable Minimum Signal Output Allows the user to adjust the minimum output between 0 and 60% of the output signal range
❑ Wide Adjustable Throttling Ranges: 5 to 50 psi and 10 to 100 psi Enables user to match the range of pressure control to specific application requirements
❑ Reverse or Direct Acting Modes Works in a variety of pressure applications
❑ Three Selectable Integration Constants Allows the user to adjust system recovery rate to setpoint pressure at slow, medium, or fast to meet application requirements

Application
A P352PN Series pressure control may be set as a proportional-only control or as a proportional plus integral control, to generate two standard analog output signals (0 to 10 VDC and 4 to 20 mA). The P352PN controls can be used as stand-alone devices or in conjunction with plug-together power, stage, and display modules.

A typical System 350TM pressure control application includes the following:
• P352PN Pressure Control
• Y350R Power Module (or 24 VAC transformer)
• S352AA-2 Stage Module
• D352AA-2 Digital Pressure Display Module
• P399 Pressure Transducer

Typical P352PN pressure control applications include:
• Condenser fan speed control
• Damper positioning
• Flow valve positioning

Operation Overview
IMPORTANT: The P352PN controls are intended to control equipment under normal operating conditions. Where failure or malfunction of the P352PN control could lead to an abnormal operating condition that could cause personal injury or damage to the equipment or other property, other devices (limit or safety controls) or systems (alarm or supervisory systems) intended to warn of, or protect against, failure or malfunction of the P352PN control must be incorporated into and maintained as part of the control system.

The P352PN control operates on 24 VAC and provides two analog output signals: 0 to 10 VDC and 0 to 20 mA.
