Yokogawa Variable Software Computing Unit, FX1
The JUXTA FX1 Series, Computing unit (Variable Software Type) receives voltage 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).
