FOXBORO 130 Series Pneumatic Indicating Controllers

FOXBORO 130 Series Pneumatic Indicating Controllers

DESCRIPTION

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.

FEATURES

HIGHLY VISIBLE AND BOLD DISPLAY

The large, brightly colored pointers, located directly behind the transparent vertical scale, provide a level of visibility and ease of reading which has become a benchmark for judging other display concepts. This system provides continuous full scale display of all variables, effective display of controller deviation, and easy scale changing without tools.

INDEPENDENT AUTOMATIC AND MANUAL CONTROL UNITS

Either the automatic control unit or the manual unit can be removed without disturbing the process. This design feature avoids costly shutdowns for controller servicing.

FULLY BALANCELESS AND BUMPLESS TRANSFER

The 130 Series Controllers feature the “integral balancing” method for bumpless transfer. After transfer, the controller simply responds at the integral (reset) rate to eliminate any error between set point and measurement. In addition to providing easy, balanceless and bumpless transfer, this scheme preserves the set point.

SIMPLE, LOW-COST MOUNTING

One multiple unit shelf can accommodate up to 10 instruments. All air connections are made when the controllers are installed in the shelf. Piping costs are minimized because each shelf has its own integral air supply header with individual air shutoff valves.

EASY TO SERVICE

The introduction of the 130 series dramatically advanced the state-of-the-art of pneumatic control systems with a unique pneumatic circuit board. This circuit board eliminates much of the tubing and many of the connections found in other controllers. All the components are located on one side of this board and are easily accessible by sliding back one side cover.

FORCE BALANCE CONTROL MODULE

The time-proven force balance control module ensures long life and dependability. The use of metal bellows with virtually no motion of the flexuresuspended mechanism provides the user with a clearly superior controller.

SPECIALIZED CONTROLLERS FOR EVERY APPLICATION

Foxboro offers the widest selection of optional accessories and unusual control functions in the industry. Among these, in addition to the normal control modes, are single station ratio, single station computer-set, auto selector, differential gap, and “batch”.

FUNCTIONAL SPECIFICATIONS

Input, Output Signal

20 to 100 kPa, 3 to 15 psi, or 0.2 to 1.0 bar or kg/cm2, as specified

Air Consumption under Normal Operation

Air Consumption under Normal Operation 0.5 m3/h at standard conditions (0.3 scfm) in automatic; 1.0 m3/h at standard conditions (0.6 scfm) in manual. Add 0.08 m3/h at standard conditions (0.05 scfm) for units with derivative action.

Control Action Reversal

The control action is reversed by a 90° rotation of the reversing switch.

Auto-Manual Transfer Unit

Auto-Manual Transfer Unit A two-position switch lever located on the front of the manual unit is used to switch directly from automatic to manual or, on controllers with integral (reset), from manual to automatic without bumping the process.

PHYSICAL SPECIFICATIONS

Mounting

These controllers are designed for flush mounting in vertical panels 3 to 25 mm (0.13 to 1 in) thick using 101 or 102 Series Shelves. Each controller requires one unit of shelf capacity. They may be calibrated for mounting in a panel inclined up to 75° from vertical with the rear of the instrument lower than the front. Specify mounting angle.

Connections

Separate electric and pneumatic connectors are located on the rear of the chassis in accordance with the standard arrangement for 100 Line Shelves.

Nameplate

White translucent plastic with 2.5 mm (0.1 in) high black letters. There can be a maximum of 2 lines with 17 characters or spaces per line.
