Automatic Pressure Control System. Dual Controller FPC-181S

Dual Controller FPC-181S

Low-price、High-performance、Compact size、and Various functionarity.

MBV-(SDⅡ)(ADⅡ)(LDⅡ)-M4-ARJ/APC

MEX-LD-ARJ/APC Series

☆ In switching of APC mode and MPA mode , it enables more versatile control.
☆ Two valves can be controlled by a single controller FPC-181S.
☆ Parameter settings can be easy to connect a personal computer1. Also, without connecting to the PLC, it is also possible to operate the system from a personal computer .
☆ It can completely seal our valve to be used in this system. Therefore can be full closed of the exhaust line as well as automatically controlling the pressure.
“Butterfly Valve MBV-(ADⅡ)(LDⅡ)-ARJ Series / Gate Valve MEX-LD-ARJ Series”
“Butterfly Valve MBV-LDⅡ-MP Series / Gate Valve MEX-LD-MP Series”
☆Auto pressure control for Leakage type of low-cost (The 20A NW25 size is also prepare with fully-closable specifications.) SDⅡ-M4-ARJ Series
☆Power failure protection is enabled by adding UPS power supply.If power failure occurred, the valve moves to the fully closed position automatically.
☆ Ethernet communication is also available as an option.

1.APC mode (Auto pressure control mode)

☆ Various control methods are selectable
①Two valves are individually controlled by signals from the two vacuum gauges.
②The two valves can be synchronized controlled by a signal from a single vacuum gauge.
③One valve can be controlled by switching the signal from two vacuum gages according to pressure.
④The two valves can be synchronized controlled by switching the signal from two vacuum gages ccording to pressure.

☆Finer pressure setting is possible.
①Maximum 8 segments(step) program by each valves can be made eight patterns.
②The PID value can be set eight patterns every each segment
③Pressure setting and time can be combined.
④ ② and ③ can be combined, and it is possible to obtain a faster response than pressure fluctuations.

☆This controller can be a wide range of pressure control by using the two vacuum gauge is switched according to the pressure .
☆ Depending on the parameter settings, vacuum gauges with linear output and log output can be used.
☆ Automatic pressure control and multi-position control are both available.From any position to target position can be fast and smooth pressure control.

2.MPA mode(Simplified pressure control mode)

☆ By entering the current (4~20 mA or 0~10V) to the controller , it enable to operate between the fully closed – fully open to the linear.
☆ Pre-registered that had been 16 position (14 position other than fully- closed , fully- open ) , it will be able to move the valve disc with a signal from the outside.

Basic specification

1. Controller 「 F P C -1 8 1 S」

In APC mode, the valve can work fast and accurately when the output signal of vacuum gaugecalculates automatically, also stable control.
Furthermore, by switching to MPA mode, current (4-20 mA) or voltage(0-10V) can be inputted directly, it can be made to operate linearly between fully-closed to fully-open.
