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. Product Specifications BRANDJohnson Controls CAPILLARY LENGTH FEET3 PSIG (KPA) RANGE240 to 600 HEATER CIRCUIT VAC120/240 VAC TIME DELAY121 sec.
