The IBA Batch Controller is an 85 to 265VAC or 12-40VDC powered batch controller for liquids that incorporates a six (6) digit 18mm LCD (liquid crystal) display, integrated back light and an isolated 4-20mA output with a programmable profile for modulating valve control. The instrument can be configured from the front touch buttons to batch volumes from 0.1 to 999,999 litres and K factors from 999,999 to 0.01 can be utilised. The instrument provides the excitation power supply for the flow sensor.
The IBL can operate in local manual mode by front panel touch switches for Batch Start, Stop & resume or in remote mode as these functions are available for external control.
The instrument accepts an input from 0 to 2KHZ and is dip switch selectable for open collector, reed, Hall, Namur and turbine signals (from 20mV peak to peak).
The IBA incorporates a six (6) digit 18mm digit height (LCD) display with integrated white LED backlight with a wide viewing angle and a viewing distance of 5 metres. The front panel switched are an embossed membrane type with positive action.
The instrument incorporates an optional RS232 serial port to drive a ticket printer with client header, batch total, accumulated total, current time, current date and batch number.
The instrument incorporates a background running total that is stored in eeprom memory during loss of power. This total can be displayed by the front total touch button and reset.
The instrument incorporates a low flow alarm. If no input pulses are received in a pre- programmed period the low flow output becomes active and the batch is cancelled and LF ERR is displayed.
85 to 265VAC of 47-63 Hz or DC to DC converter from 12 to 40VDC. An adjustable transducer power supply of 8 to 20VDC at 50mA is incorporated in the instrument.
CE for EMC compliance and electrical safety.
Four membrane switches on the front panel allow the batch quantity to be set and batching operations to be started, stopped, resumed and reset. When the batcher is running the DISPLAY button can be used to show the background total.
The instrument has a universal AC power supply that allows it to be powered from 85 to 265VAC and 47 to 63 Hz. Alternatively it can be supplied as a DC powered instrument that operate from 12 to 40VDC.
The batch size is set from the front panel. Pressing the start button will energise relay one and start liquid flow. It will stay energised until the end of batch is reached and then de-energise. The isolated 4-20mA control output with five point programmable profile will ramp the valve open to set point one, hold to set point two, ramp down to set point three, hold set set point four and ramp valve down to batch complete., The batch process can be halted at any time with the stop button and restarted which will cause the batch to continue from where it stopped but not reset the batch counter.
