The Flucon FC600 series Explosion proof I/P (current to pressure) Valve Transducers convert a 420m electrical current signal to proportionally linear pneumatic output. The unique conversion technology utilizing open loop control provides a high level of accuracy and repeatability for the operation of actuated valves. A low mass control circuit provides consistent output in high vibration applications. This compact unit is housed in an explosion proof enclosure that is designed for pipe, bracket or direct manifold mounting. This explosion-proof and intrinsically safe field device is available with an integral volume booster or as a low-flow signal converter that directly mounts to a pneumatic valve positioner. The Flucon FC600 series has worldwide agency approvals for use in hazardous areas. Multiple choices for wiring and porting simplify installation and decrease the time required to do so. In addition to standard wall, panel or pipe mounting, optional DIN rail and manifold mounting kits are available. The Flucon FC600 series Multifunction Manifold provides a common supply port and individual shutoff valves for sets of 3, 5, 10 or 15 units. Integrated Characteristics :

• Compact Design.
• Low Air Consumption.
• Low Power Consumption.
• Integral Volume Booster
• Flexible Adjustments of Zero & Span.
• Standard Process Inputs.
• Vibration and Position Insensitive.

DescriptionThe Flucon 5110 FC series transducers are ideally used to convert current or voltage input signal to a linearly proportional pneumatic output pressure. This versatile instrument is rugged and reliable force balance transducers for use in both process control and industrial applications, tor standard process control applications which typically utilize 3 to 15 psig output and industrial & high pressure application which typically utilize pressure output up to 120 psig. Flucon 500FC series transducers combines low cost, high accuracy and minimum air consumption with proven technology. Versatile design features and rugged, oorripact housing with a choice CMRI and ATEX* approved versions tor explosion proof or intrinsically sate operation when used with a suitable barrier. Principle of OperationThe Flucon 5110 FC series transducer is a force balance device in which, when electrical current is passed through the coil of transducer, a magnetic 1ied is created which acts on the magnet assembly; casuirg die anvil Sl diaphragm to move away lrorn or forward the nozzle (flapper nozzle) depending on the direction of currentt low. Motion at the nozzle assembly is proportional to the amount of current passing through the coil. The flapper/anvil move away from or forward onwards the nozzle creates back pressure which acts as pilot pressure to an integral booster relay. when input electrical current increases lor decreases tor reverse actingl causes proportional output pressure increases. Iero and Span are calibrated by turning easily accessible adjusting screws on the font lace of the unit. The zero adjusting screw causes the nozzle to move relative to the flapper/anvil. The span adjusting screw is a potentiometer that limits die current through the coil. Thermistor circuit in series with the coil provides temperature compensation. Download

Principle of Operation

The Flucon 500 FC Series transducer is a force balance device in which, when electrical current is passed through the coil of transducer magnetic field is created which acts on the magnet assembly, casuing the anvi & diaphragm to move away from or forward the nozzle (flapper nozzle) depending on the direction of current flow. Motion at the nozzle assembly is proportional to the amount of current passing through the coil.

The flapper/anvil move away from or forward towards the nozzle creates back pressure which acts as pilot pressure to an integral booster relay. when input electrical current increases (or decreases for reverse acting) causes proportional output pressure increases.

Zero and Span are calibrated by turning easily accessible adjusting screws on the front face of the unit. The zero adjusting screw causes the nozzle to move relative to the flapper/anvil. The span adjusting screw is a potentiometer that limits the current through the coil. A thermistor circuit in Series with the coil provides temperature compensation.
