The ABB PSTX105 soft starter, order code 1SFA898109R7009, is an active-production motor-starting component rated for main circuit voltages from 208 to 600 V AC. The 24 V DC control circuit keeps it compatible with standard PLC-level control signals — no separate control transformer needed for the logic supply.
Integration Notes
Mounts on DIN rail in a standard control panel enclosure. The 24 V DC control circuit simplifies wiring — just a single supply from the PLC output card or a dedicated 24 VDC power supply. Verify the free-wheel diode polarity on any shunt loads before commissioning; the soft starter's internal suppression expects correct orientation. CAD dimensional drawing 2CDC001079B0201 covers the footprint for panel layout.
