520 Digital Weight Indicator

355 Picture


MODEL 520 DIGITAL INDICATOR:

Ideal for Process weighing applications, the 520 is available with Analog output, Ethernet 10, Ethernet 10/100, Device Net, Allen Bradley Remote I/O or Profibus output options.  The 520 is  designed for mounting in an existing or new control panel taking limited panel space. Large .75" display digits make this indicator easy to read from a distance. Digital inputs and outputs provide greater flexibility in control schemes.
