Sequential controller-Top Manufacturers, Function, specification, Output, Application & Special offers

Sequential controller is also known as Dust collector Controller has been designed to operate the pilot valves used on dust collector Equipment. Light emitting diodes (LEDs) provide visual indication of which dust collector valve is being energized as well as “Power On” indication. The number of sequenced steps is adjustable from 2 through 10.Controls are provided to adjust the length of time between valves being de-energized (Pulse Frequency / Off time) and the length of time that the valve is energized (Pulse Duration / On time). Sequential controller components control all timing and logic Functions.

Two independent methods of starting and stopping the Controller are provided. The first method will automatically stop the sequence and reset the Controller to the first valve position whenever A. C. power is removed and then reconnected.

The second method is by a remote control contact connected to the terminals provided. When the remote contact is opened, the sequence stops. When the remote contact is reclosed, the sequence continues from the previous

Sequential controller Operation:

The catalog SQP-1 Sequential Controller provides timed sequential energization of connected loads. When power is applied to the Controller, the “Power On” light emitting diode (LED) provides visual indication and pilot valve number 1 is immediately energized. “Output 1” LED provides visual indication of this event.

The pilot valve will remain energized for the length of time as indicated by the setting of the “Pulse Duration / On time” control. Note that the calibrated dials are for approximate settings only and if exact times are required, they must be measured.

Pilot valve number 2 will automatically be energized at some time interval after pilot valve number 1 has been de-energized. This length of time will be as indicated by the setting of the “Pulse Frequency / Off time” control, “Output 2” LED will provide visual indication that this event is occurring. The Controller will continue to sequentially energize the pilot valves until the power is removed.

Additional Parameters for feedback type as follows :

A] 1) System Ok / Timer Healthy – Potential free ‘NO’ relay contact.

2) Sequence ‘ON’ / D.P. Low – Potential free ‘NO’ relay contact.

B] 1) Auto Mode – Channels activated in sequence as per ‘On’ and ‘Off’ time.

2) Manual mode – Output channels are activated by pressing push button on PCB near Auto /Manual switch channel in sequence

MANIKS Sequential controller Advantages Over Other Manufacturers

Ensured availability:

Other suppliers may be limited to a single


Distribution point:

We provide localized distribution across the globe. MANIKS offers its most popular products for dust collectors via quick-shipment programmers — including “Express”.

Superior support:

With more than 100 professionals handling direct sales, plus more than 140

Distributors in Europe alone, MANIKS has you covered. Ask our technical experts anything about specific-cation, installation, performance, or maintenance of dust collector air system components. You’ll get fast and most accurate answers.

Unequalled quality and reliability:

We build our products for rock-solid, repeatable operation over long lifetimes. For instance, our pulse valves are rated at 1 million cycles, with internals designed and constructed for tight seating. You save expensive compressed air — and get maximum pulse pressure for the best performance, 

Why Maniks Dust Collector

A variety of manufacturers make dust collector valve, cylinders, and other auto-mation components that control the flow of compressed air through industrial dust collector systems. Performance and cost-effectiveness are essential in all such systems.

The critical difference in MANIKS dust collection & other is its unique combination of quality, performance, and value with quick shipment of standard components — as well as consistent technical support and service for easy assembly, reliable operation, and efficient maintenance. For decades, we’ve been a leading supplier to engineering contractors and to end users of sequential controller in a wide range of industries, including the following:

  • Lime and cement processing
  • Grain, agriculture, and feed
  • Metalworking (welding, grinding, cutting …)
  • Food processing
  • Heavy industries (iron, steel …)
  • Pharmaceutical (Powder …)
  • Power engineering (coal-fired power plants)
  • Wood machining

Our high-efficiency designs permit dust collector manufacturers to create more cost-effective systems. Our high flow and pressure ratings allow those systems to operate at peak performance. And our robust design means longer life and reduced downtime. From high-reliability products to easy-replacement valve rebuild kits — both at competitive prices — MANIKS provides superior solutions for dust collector systems. 

Maniks Special Offers:
