The Siemens 6SL3056-4AA32-3AV0 is a panel-mount ammeter purpose-built for the SINAMICS V50 drive family. It reads 0-230 A on the scale, driven by a standard 0-20 mA analog input signal — the loop you'd pull from a current transformer or drive analog output. That 0-20 mA input is the key fit detail: if your V50 or control card outputs 4-20 mA, you'll need a scaling resistor or a different meter; this one expects the full zero-based span.
Active and mature per the Siemens lifecycle tracker. REACH compliance is declared on the current candidate list — documentation available with the order.
Mounts in the standard SINAMICS V50 operator panel cutout. The 0-20 mA input loop is passive — the meter draws its signal from the drive's analog output or an external transducer. Verify the loop power source: if the V50 analog output is active (sourcing), wire directly; if it's passive (sinking), you'll need an external 24 VDC supply in series. The scale is fixed at 0-230 A, so the drive's current scaling parameter (p2002 in SINAMICS) should match that full-scale value for a direct read.
