The NEW Contrec 424 Batch Controller is designed to flow applications where precise measurement and control of batch quantities are required. Batch total, flow rate, accumulated total and preset value hence to displayed in engineering units on the large LCD.

The Contrec 424 will interface to most pulse outputs flowmeters

Batch Features

Automatic Overrun Compensation: Based on previous batches the 424 Batch Controller will compensate automatically for any overrun which generally 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-energized, while the open collector output signals an alarm.

Remote Start/Stop: Rear terminal strip ready to connect remote push-button switches, to start and stop batches.

Auto Restart: Automatically restart the batch after a preset time delay can be set to Contrec 424.

Count Up/Down: The Contrec 424 Batch Controller can be programmed to count up from zero, or to count down from the set batch quantity.

End of Batch: An open collector transistor output ready for the end of the batch signal.
