424 Batch Controller by Contrec

Contrec 424 Batch Controller

Contrec's 424 Batch Controller is suited to flow applications where precise measurement and control of batch quantities are required. Batch total, flow rate, accumulated total, and preset value can all be displayed in engineering units on the large LCD display.



The 424 will interface to most flowmeters with versions available for pulse outputs.

  • Dual relay outputs
  • Overrun compensation
  • Remote operation
  • No flow alarm
  • Custom headers for ticket printing
  • Displays batch total, preset quantity, flow rate and accumulated total
  • RS485 & RS232 output
  • Adjustable backlight
  • Software control of flow input type and output voltage
  • Universal mains input voltage
  • Optional 4-20mA output

424 Batch Controller Features

Batch Features
Automatic Overrun Compensation
Based on previous batches. the 424 will automatically compensate for any overrun which may be caused by slow-closing valves.

Batch Limit
A maximum batch quantity can be programmed during set-up so that the operator cannot enter a batch size that exceeds this limit.

Signal Time-out
If the flow signal cuts out midway through a batch, the output relays are de-energised, and an alarm is signaled via an open collector output.

Remote Start/Stop
Remote push-button switches can be connected to the rear terminal strip, to start and stop batches.

Auto Restart
The 424 can be programmed to automatically restart the batch after a preset time delay.

Count Up/Down
The instrument can be programmed to count up from zero or to count down from the batch quantity.

End of Batch
An end-of-batch signal is provided via an open collector transistor output.
