BATCH CONTROLLER - Model 414
The 414 Batch Controller is suited to flow applications where precise measurement and control of batch quantities is required. Batch total, flow rate, accumulated total and preset value can all be displayed in engineering units on the large LCD display.

The 414 will interface to most flowmeters with versions available for pulse and analog inputs.

Features

• Dual relay outputs
• One or two stage valve control
• RS232 and RS422/485 computer/printer interface
• Ticket printing with time and date
• Automatic Overrun Compensation
• Batch Limit
• Signal Time-out
• Remote Start/Stop
• Auto Restart
• Count Up/Down
• End of Batch Signal
• Scaled pulse output

MODELS AVAILABLE

Model 414A
Analog input version with both linear and square law input relationships.

Model 414B
Frequency input version that will accept pulse and open collector inputs from opto-sensors or Hall effect devices.

Model 414D
Frequency input version with an input conditioning card capable of accepting mV signals from coils, 2-wire proximity sensors, reed switch inputs and most other pulse type signals.

Model 414H
For applications where batches are very short (<15 seconds) the 414H features a response time of less than 20ms
The input is identical to the 414D but the scaling factor is limited to 4000 and the input frequency range is limited to 8kHz

Model 414Q
Quadrature input version where the flowmeter produces two pulse or square wave signals 90° out of phase. Through the phasing of signals, forward and reverse flow can be detected.

Model 414LA
4-20mA temperature input version with temperature correction for general chemicals, petroleums and LPG to API tables.

Model 414LR
Similar to 414LA except that the 414LR has a direct RTD temperature input.

• Optional RS232/422/485 interfaces for computers
  and printers
• Ticket printing with time and date
• Displays batch total, preset quantity, flow rate and accumulated total
• Automatic Overrun Compensation
• Batch Limit
• Signal Time-out
• Remote Start/Stop
• Auto Restart
• Count Up/Down
• End of Batch Signal
• Scaled pulse output                                                                 Download 430D Datasheet in PDF format

BATCH CONTROLLER Model 214D
The Model 214D Batch Controller is designed for flow applications in hazardous areas, where the precise control of batch quantities is required.

The 214D will accept pulse or frequency flow signals generated by turbine, positive displacement, paddle wheel or other flowmeters which produce intrinsically safe signals.

Features

• CENELEC and CSA US/C approved
• Displays Batch Total, Accumulated Total and Preset
  
• One or two stage valve control
  
• Watertight to IP67 (Nema 4X)
  
• Wall or pipe mounting
  
• Fully programmable                                                                    Download 214D Datasheet in PDF format
