We are a developer & system solutions of automation technology and devices geared toward the manufacturers of Bulk Handling & Air pollution System products. Our latest development is a Fully Programmed, On Demand, Bag House Controller PLC. This device measures, and communicates (RS485 Modbus RTU Protocol) in real time, the differential pressure of dust collector along with all other major parameters in process. Such equipments are used in Boiler houses, foundries, cement plants, process plants, steel plants etc.

This low cost controller handles Total Bag House Course Of Action to fullest extent The controller functions are,

  1. Solenoid firing-with ON & OFF time programmable & No of Valves to be fired Extra clock [2 wire] for additional solenoids firing in case of expansion of more Bag rows With X'CALIBUR make Bag House sequencers. [Future expansion]
  2. Facility for detecting faulty solenoid operation (additional cost)
  3. Differential Pressure control via High & Low set Points for ON DEMAND PULSING {using DWYER [Model 616W-20B-LCD] Differential pressure gauge transmitter with LCD Display}
  4. Bag leakage/torn bag detection & eye pleasing annunciation for the same
  5. Direct Function key to Override On demand (F1) & to operate in timed mode
  6. Direct function key for Manual test of Pulse valve (F2)
  7. Direct function key for crash Mode operation if required (F3)
  8. Fan Power control for optimised (PID) power use for operation via VFD drive
  9. Rotary air lock zero speed monitoring with hopper Level control integrated.
  10. Hopper bulk discharge system Pneumatic Vibrator automation.
  11. Local or Remote operation from direct function keys or via SCADA Software
  12. Additional 3-Temperature/ Weight/Level 4-20 mA Transmitters can be hooked to system for further process automation.

The operation procedures are fully programmable and can be set to from Well-designed HMI Numeric key pad with 20X2 LCD Display. The PLC device is self-contained and can be used as an automation device on the production floor or in a lab situation.

Functional tracking measurements & control can be accomplished via SCADA software with RS485 Modbus or Profibus protocol for computer interface or other PLC /DCS systems.
