Svi 1000 Positioner -

While modern plants are rushing toward Foundation Fieldbus and Profibus PA, the reality is that 70% of brownfield installations still run on 4-20 mA loops with HART overlay. The SVI 1000 capitalizes on this beautifully. It doesn't force you to rip out your legacy wiring. It sits on the existing two wires, sipping less than 20mA, while superimposing digital diagnostics onto the analog control signal.
