MA5 Free Range Type Distributor
Brand: Yokogawa Electric CorporationThe MA5 is a plug-in type distributor that is used in combination with a two-wire type transmitter to convert the transmitter’s 4-20 mA DC signals into isolated DC current or DC voltage signals.
Features- Output range setting, selection of square root extractor and breakpoint linearization (breakpoint setting), I/O adjustment, I/O monitoring, and loop back test can be made using the optional Parameter Setting Tool (VJ77) or Handy Terminal (JHT200)
- The operation indicating lamp shows the operation status, abnormalities in a setting etc
- I/O adjustment can be made using the switches on the front panel of the MA5 without a setting tool such as Handy Terminal
- Supports BARD-800 and -810
