Product details

What this soft starter does on your line

The 3RW5224-1AC05: The 24 V control supply powers the logic and communications; the analog output is configurable as 4-20 mA or 0-10 V for feedback to a PLC or SCADA. Soft Torque and Pump Ramp Down are built in — no extra option card needed for those profiles.

Mounting and clearance — what fits in the panel

Screw fixing on a vertical surface, with +/-10° rotation allowed and tilt forward or backward. The enclosure dimensions are 306 mm high, 185 mm wide, and 203 mm deep. Clearance requirements: 100 mm above, 75 mm below, 10 mm forward, 5 mm at the sides, and 0 mm backward — so it can sit flush against a backplane. That 0 mm rear clearance is unusual; it means no service gap behind the unit, which helps in shallow enclosures.

Communications and control — fieldbus fit

This unit ships with onboard PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP — no separate communication module to buy and slot. It also supports PROFINET standard and PROFIenergy (in connection with the PROFINET Standard communication module). For a line that already runs Modbus TCP or EtherNet/IP, this is a direct drop-in; no gateway needed. Remote reset is handled by cycling the 24 V control supply.
