Rated for 208-600 V AC at 50/60 Hz, with a control supply of 100-250 V AC and a separate 24 V DC control circuit for the logic side. The ramp time is adjustable from 1 to 120 seconds, giving you the window to match the acceleration profile of the load — short for low-inertia fans, long for high-inertia centrifuges. ## Fieldbus & I/O Communication options cover Modbus-RTU, Modbus-TCP, Ethernet-IP, EtherCAT, DeviceNet, CANopen, Profibus, Profinet, BACnet-IP, and BACnet-MSTP — the PSTX30 is a universal node that fits into any control architecture without a gateway. Analog outputs are configurable for 0-10 V, 0-20 mA, or 4-20 mA, letting you feed motor current, voltage, or power factor to a PLC or remote display. Dedicated run, fault, bypass, and overload signal relays are onboard, so you get hardwired status without pulling from the fieldbus. ## Protection & Warnings Built-in electronic overload protection eliminates the need for a separate overload relay, and the protection suite covers current imbalance, earth fault, locked rotor, phase reversal, under/over voltage, and user-defined limits. Warning outputs flag conditions like current imbalance, underload, faulty fan, motor runtime limit, THD(U), and SCR thyristor overload — useful for predictive maintenance before a trip occurs.","metaTitle":"ABB PSTX30 Soft Starter 1SFA898103R7000, Auto Phase Sequence","metaDescription":"ABB PSTX30 soft starter 1SFA898103R7000 with auto phase sequence detection, ramp time 1-120 s, 208-600 V AC.
