Type 3511 & Type 3521-Digital Enclosure Regulator

Brand: Marsh Bellofram Group of Companies

Type 3511 single- and Type 3521 double-loop digital servo pressure controllers, available with analog or digital outputs, combine all the advantages of reliable solenoid valve technology in a rugged weatherproof enclosure for greater durability and performance.

The configurable units feature forward flow equivalent capabilities of up to 19 SFCM for standard industry electronic regulators or I/P transducers, when using the built-in air volume booster (Type 3511). Reverse flow (exhaust) of up to 7 SCFM is possible.

With available pressure ranges from 0 to 150 psig, the controllers offer local keypad programming option (with optional four-digit display) or RS-485 digital communications for PLC or PC digital control, housed in a rugged, weatherproof enclosure.

Units offer dual solenoid valves with an integral pressure transducer and advanced microprocessor control, as well as Proportional-Integral-Derivative (PID) control. The double loop version (Type 3521) permits 0-10 VDC feedback from a remote sensor.
