P352P Series
Electronic Proportional Plus Integral Pressure Controls:
Static Pressure (W.C.) and PSI Series
Code No. LIT-1922440
Issued November 18, 2008
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 P499 Pressure Transducers. (See
Selection Chart)
. All P352P models can use
the Y350R Power Module.
