FOXBORO 43AP-FA42D/PB-AA 43AP Pneumatic Indicating Controllers

43AP-FA42D/PB-AA  Foxboro 43AP Pneumatic Indicating Controllers

WIDE SELECTION OF MEASURING

ELEMENTS

Automation Service products offer a variety of

element constructions. This versatility enables

the 43AP Series Pneumatic Indicating Controllers

to be applied to virtually any process.

WIDE CHOICE OF CONTROL MODES

On-off, proportional, proportional plus

derivative, proportional plus integral (reset),

proportional plus integral plus derivative, and

differential gap actions are available.

BROAD RANGE OF INTEGRAL (RESET) AND

DERIVATIVE ADJUSTMENTS

The integral unit has the complete range from

0.01 to 50 minutes, and the derivative unit from

0.05 to 50 minutes.

VARIETY OF OPTIONS

These controllers are available with an extensive

list of optional features. Among these are

internal bumpless automatic-manual transfer

stations (two types), “batch” function, and remote

pneumatic set poin

ACCURACY UNAFFECTED BY MOUNTING

STRESSES

VERSATILE MOUNTING

Both the control unit and the measurement

element are mounted on a rigid steel plate. Thus,

these components are isolated from case stresses

due to mounting, and dependable accuracy is

ensured.

POWER FAILURES DO NOT INFLUENCE

PROCESS-DRIVEN INDICATION

A power failure and the likely subsequent loss

of supply pressure do not influence the process

driven indication.

WEATHERPROOF CONSTRUCTION

A glass fiber reinforced case and a gasketed

door with a shatterproof polycarbonate window

meet IEC IP53 and provide the environmental

protection of NEMA® Type 3.

Instruments may be mounted in a panel, on a

f

lat surface, on a continuous vertical pipe, or on a

vertical pipe stub.

INTERNAL BUMPLESS

AUTOMATIC-MANUAL TRANSFER STATION

This option provides bumpless-balanceable

transfer between automatic and manual control

by simple 2-step procedure. Accidental transfer

is avoided because the door must be opened to

gain access to the transfer station.
