434 – Batch Controller

Product Details

Description

The 434 Batch Controller is suited to flow applications where precise measurement and control of variable batch quantities is required. Batch Total, Flow Rate, Accumulated Total and Preset Value can all be displayed in engineering units on the back-lit LCD display. The 434 will interface to most flowmeters generating pulse or frequency outputs.

An RS232 and  RS485 option is available for interfacing to computers and printers. The interface allows the Batch Controller to be fully controlled from a computer. Software drivers are included for a number of printers and can print a ticket with time and date, a sequential delivery/batch number and the batch and accumulated totals.

Operation

The instrument will operate from 14 to 28V dc or from 110 to 220V ac mains.

Keypad operations are straightforward and four LED’s indicate the operational status at all times. The unique keypad simplifies operation, making the instrument suited to use by operators with minimal training. Four operational keys and a full numeric keypad on the front fascia, enable the batch quantity to be set, and batch operations to be started, paused, stopped or reset.

Automatic Overrun Compensation Based on previous batches, the 434 will automatically compensate for any overrun which may be caused by slow closing valves.
