WX3 mV Input/Variable Software Computing Unit

Brand: Yokogawa Electric Corporation

The JUXTA WX3 Series, Computing unit (mV Input/ Variable Software Type) receives mV input signals, applies various computing functions to them, and outputs isolated DC current or DC voltage signals to controllers or recorders. 

The computation parameters, zero points, and spans can be set and modified using a Handy Terminal (JHT200).
