BAG FILTER CONTROLLER (BFC) Relay Output
Description
Function:
Bag Filter Controller (BFC) is Solid State Sequential Timer, designed to control the cleaning cycle of On-Line Bag Filters with adjustable ON, OFF & Pause Timings. It is available in various models to suit different output requirements. Custom Built Timer Panels are also available, which are designed as per customer specification.
| State of the art, Solid State Design. |
| Input interlocks to the timer are potential free contacts from D.P. Switch and Remote ON Command from PLC. |
| Solenoid is energized at Zero Crossing of AC cycle to reduce solenoid inrush current. This improves solenoid and timer circuit life |
| Separate terminals for solenoid phase and neutral connections, hence no need of separate junction box |
| Surge suppressors are provided to protect output circuit from high voltage surge generated during solenoid operation |
| Operating sequence can be started or stopped from Remote location or through PLC / DCS system |
| Manual testing Facility |
| Sequence Termination Facility at any desired channel |
| Adjustable ON Time (Solenoid energization time) OFF Time (Time gap between operation of two successive channels), & PAUSE Time (Time gap between operation of two successive cycles). PAUSE time is optional |
| Potentiometer provided for adjustment of Timings |
| Control Supply 110V AC or 230V AC. Unit suitable for 24V DC Control Supply or 24V DC solenoid voltage is also available optionally |
| These Timers can be used for 110V AC or 230V AC or 24V DC solenoids |
| Timer (Supply) ON or Purging ON or Cycle Complete Feedback available |
| Models with higher output channels (up to 34 channel Max.) available. For more than 34 channels, Microprocessor / Microcontroller based models (MBFC series) available |
| Sheet Steel, IP-55 grade enclosure, suitable for Field Mounting. IP-65 grade Enclosure available optionally |
Bag Filter Timers are used in De-Dusting and Process Bag House in various industries such as: Aluminium, Asbestos, Carbon Black, Clay, Detergent, Gypsum, Limestone, Saw Dust, Steel / Sponge Iron, Solvent Extraction, Non-ferrous, Bagasse Dust, Cement, Food Grain Handling, Fly Ash, Iron Ore, Sugar, Chemicals, Fertilizers, Flour, Tea, Ceramic, Coal, Paint Pigments, Milk Powder, Soda Ash, Battery Industries, Wood, Spices etc.
