Type 3521- T3521 Digital Weatherproof Regulators
The 3521 offers solenoid valve technology with forward flow equivalent to standard industrial electronic regulators or I/P transducers. Available with local keypad programming option or RS-485 Digital Communications for PLC or PC control. Dual solenoid valves with internal pressure sensor and advanced microprocessor control. A built-in air volume booster provides the 3521 with forward flow up to 17 SCFM. Proportional - Integral - Derivative (PID) control. Ranges from 0 to 150 psig. Reverse flow (exhaust) of up to 7 SCFM. The double loop (3521) option permits 0-10 VDC feedback from a remote sensor. The keypad is available with a four digit display of the output pressure.
