Ashcrfot Pressure volume controller models AVC1000 and AVC3000.

These instruments are used wherever accurate chart records, precise indications, or control of the measured

variable are required for efficient process management. A wide variety of Foxboro field-proven and dependable

measuring elements are used to receive the measured signal

The 40M Series Recorders and Indicators continuously record or indicate measurement of one

or more process variables. They provide high accuracy, local reading, and fast response to the

measured signal change. They accommodate up to four pens, or one or two pointers.

The 40M Series Controllers receives mechanical,pneumatic, or electrical inputs from an integrallymounted

measuring or receiving element; compare it to a set point; and as a function of the control mode,

produce a standard pneumatic output signal to modulate a remote final operator that may be as far

as 100 m (300 ft) distant. They control one or two measurements, and either record or indicate the

variable.

MANY CONFIGURATIONS – NUMEROUS RANGES

 

WIDE SELECTION OF CONTROL MODES

 

HIGH-QUALITY ENCLOSURE CONSTRUCTION

 

These instruments are used wherever precise chart records, indication, or control of pressure measurement is

required for efficient process management.

 

These instruments either record on a circular chart, or indicate on a sector scale or concentric scale. The

recorders and sector scale indicators are available with up to four pens and two pointers, respectively.

The concentric scale indicator is available with one pointer.

 

The controllers control one or two measurements and either record or indicate the variable.The control

elements transmit a standard pneumatic signal to a final operator that may be as far as one hundred

metres (three hundred feet) distant.

These controllers are designed for high-density control room mounting and are used wherever precise control is required for efficient process management.

The basic controller is the 130M Series featuring manual set point adjustment. The 130P Series is

similar to the 130M except that the set point is pneumatically adjusted by a remote signal. The 130F

Series is similar to the 130M except that it includes a Remote/Local switch which allows either manual or

pneumatic adjustment of the set point.

The Foxboro 716C is a powerful compact,1/16 DIN, microprocessor-based temperature controller that offers a variety of standard features commonly found only as options with other models.

FEATURES

• Dual 4-digit LED display

• Universal input (T/C, RTD, mV, V, mA)

• Adaptive Auto-Tune

• NEMA 4X

• UL, CSA rating

• PID control with 0 to 20 mA or 4 to 20 mA

control signal

• Time proportional control

• Safety lock-out function prevents unauthorized

configuration

• Two independent set points selectable from

external input contact

• Up to two independent alarms configurable

with automatic or manual reset

• Instrument configurable by keyboard or through

serial link

• Output “Turn Off” function, turns off the output

and allows the controller to operate as an

indicator

• Opto-isolated RS-485 serial communication

interface with Modbus (optional)

• 24 V ac/dc supply (optional)

• Conforms to the applicable European Union

directives (symbolized by the “CE” Logo

marking on the product)

 

The 716C offers advanced features, usually found

in higher priced models, enabling quick start-ups,

safe operation, and precise measurement readings.

 

Quick Start-Ups

The 716C is equipped with a proprietary self-tuning

algorithm, SMART (see Figure 1). During start-up

and control, the SMART algorithm continuously

monitors the process variable and automatically

adjusts the PlD parameters according to the

response of the process variable. The advantage of

this continuous self-tuning algorithm is its ability to

operate without injecting any artificial change into

the system
