Description The NEW Contrec 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 hence to displayed in engineering units on the large LCD display. The 424 will interface to most flowmeters with versions available for pulse outputs.
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-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 instrument can be programmed to count up from zero, or to count down from the batch quantity.
End of Batch An end of the batch signal is provided via an open collector transistor output.
