MXD Universal Computing Unit
Brand: Yokogawa Electric Corporation
This plug-in type universal computing unit receives DC current or DC voltage signals, applies various computing functions to them, and then converts them into isolated DC current or DC voltage signals.
Features- The optional Parameter Setting Tool (VJ77) or Handy Terminal (JHT200) can be used for the setting changes of various parameters such as computing functions or input/output ranges, the setting changes of programs, and the test outputs
- The operation indicating lamp shows the operation status, abnormalities in a setting etc
- Without a setting tool such as Handy Terminal etc., outputs can be adjusted and forced contact outputs can be turned on or off using the switches on the front panel.
