Description
The P352P Electronic Proportional Plus
Integral Pressure Control Series has two
proportional outputs of 0 to 10 VDC and
0 to 20 mA. Proportional plus integral (PI)
control is an option to hold setpoint,
regardless of load shifts on a system.
Two models cover the pressure ranges of 0.5 to
5 in. W.C. and 0.025 to 0.25 in. W.C., and use the
DPT2640 Pressure Transmitters. Three models
cover the pressure ranges of 0-100 psi, 90-250
psi, and 240-600 psi, and use the P399 Pressure
Transducers. (See Selection Chart) All P352P
models can use the Y350R Power Module.
Features
• field selectable proportional only or
proportional plus integral control
• surface of DIN rail mounting
• ten segment LED displays percent of output
signal
• field selectable reverse/direct acting mode
• minimum output adjustment
• 5-pin connectors eliminate wiring between
modules
Applications
• dual static pressure control
• building pressurization
• condenser fan speed control
• damper positioning
• flow valve positioning
To Order
Specify code number from the selection chart
below, along with the corresponding pressure
sensor. If required, power, stage, and display
modules may be ordered separately.
