Inputs and Outputs
  • 1 digital input „reset of weight value“
  • 1 digital input „zero setting of belt scale“ (used by automatic in-flight compensation)
  • 1 digital output "scale o.k." (pulse output)
  • 1 digital output, pulse output, flow rate per pulse adjustable
  • 1 digital output weight value < 5 % (adjustable, used by the automatic in-flight compensation)
  • 1 analog output 0 - 10 V or 4 - 20 mA (not required for closed-loop control)
Interfaces
  • Ethernet interface TCP/IP
  • Alternatively, the Ethernet interface can be used for “Modbus over IP” (Modbus TCP Port 502)
  • Serial interfaces RS 232 / RS 485 e.g. for connection to WÖHWA remote displays LCD83/5 , LCD140/6 or ADI550 for the visualization of the current measurement value or the output
  • Protocols for reading out the output, belt speed, flow rate, totalizing memory, etc.
Software for belt scale

The weighing terminal is supplied with a software for belt scales including visualization of weighings per day, work shift logs, counter functions, automatic e-mail transmission, and parameter file for the configuration of the output recorder software. System requirements for use of the software: A PC with ETHERNET connection and Windows 7 or later.
