Introduction Overview The 515 BR03 application is a batching ratio controller for delivery of preset quantities at preset ratios using mass frequency inputs. Batch control can operate in preset or on-off modes, while flow control can be set to various loop control modes.
Totals are output as pulses and rates are output as 4-20 mA signals. One output is standard, a second output is available as an option. 515 BR03 - 15 August 2021...
The software is a Windows based program that is freely available from the download section of the Contrec website. The program can be used to create a custom version of an existing application to be saved for backup purposes and/or to generate a PDF of configuration report for record keeping.
Properly shielded and grounded cables and connectors must be used in order to meet FCC emission limits. Contrec Ltd is not responsible for any radio or television interference caused by using other than recommended cables and connectors or by unauthorized changes or modifications to this equipment.
