The programmable sequential controller is designed specifically for use with pneumatic dust collector systems. It is used to control the solenoid of the diaphragm valve in order to program the pulse jet sequence of the valves. LED lights serve as indication of status of pulse position and timing.
Both the pulse jet timing and duration of each pulse jet could be adjusted by the logic circuitry. The controller has 2 independent "ON" and "OFF" methods, the 1st is when the AC power supply is cut off, the controller will shut down. When the AC supply is reconnected, the controller will automatically revert to its initial default settings. The 2nd method is to employ the use of the controller"s remote contacts (R,C,A) as the controlling signal.

The sequential collector uses a microprocessor to control the pulse jets of a diaphragm valve through the electrical solenoid of the valve. The controller has 2 rows of 7 segment digital display. The first row displays the diaphragm valve number to be activated next, the 2nd row displays the time left before it activates the next valve. The pulse jet timing, duration of each pulse jet and the number of valves to be controlled could be set to user"s requirements. Also, the controller is able to be programmed to automatically execute the pulse jet cycle even after the system shuts down. The user just needs to configure all settings through the buttons on the face of the board. The controller is both user-friendly and serves a wide range of applications and will definitely satisfy all requirements of the user..
