The built-in electronic overload replaces a separate thermal overload relay — one device handles both starting and protection, saving panel space and wiring. The ramp time is adjustable from 1 to 120 seconds, which means you can tune the acceleration profile for a high-inertia fan or a loaded conveyor without adding an external timer. The control circuit runs on 24 V DC, standard for PLC-driven panels; the main control supply accepts 100...250 V AC, so it can share a control transformer with contactors. ## Fieldbus and integration This softstarter speaks ten fieldbus protocols natively: Modbus RTU, Modbus TCP, EtherNet/IP, EtherCAT, DeviceNet, CANopen, Profibus, PROFINET, BACnet IP, and BACnet MSTP. No external gateway is needed for most automation networks — it connects directly to the PLC or building management system. The analog outputs provide 0-10 V, 0-20 mA, or 4-20 mA signals for external metering or drive profiling. ## Protection and diagnostics The protection suite covers earth fault, phase reversal, locked rotor, voltage imbalance, and user-defined conditions — 20+ protection functions in total. The warning list gives early alerts for fan failure, thyristor overload, harmonic distortion, and motor runtime limits, so a maintenance team can act before a trip. Three status LEDs — red for fault, green for running, yellow for protection — give a quick visual at the cabinet door.","metaTitle":"ABB PSTX37-690-70 Softstarter, 1SFA898204R7000, 208-690 V AC","metaDescription":"ABB PSTX37 softstarter 1SFA898204R7000 with auto phase sequence detection, 208-690 V AC, built-in electronic overload, multi-protocol fieldbus.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Soft Starters"],"specifications":{"Function":"Auto phase sequence detection","Ramp Time":"1 ... 120 second [unit of time]","Communication":"Modbus-RTU; Modbus-TCP; Ethernet-IP; EtherCAT; DeviceNet; CANopen; Profibus; Profinet; BACnet-IP; BACnet-MSTP","Terminal Type":"Cable Clamp","Analog Outputs":"0...10 V, 0...20 mA, 4...20 mA","Warning Details":"Current imbalance warning; Current underload warning; Electronic overload Time-to-trip; EOL warning; Faulty fan warning; Locked rotor warning; Motor runtime limit warning; Over voltage warning; Phase loss warning (for standby); Power factor underload warning; Short circuit warning (for Limp mode); THD(U) - Total Harmonic Distortion warning; Thyristor overload warning (SCR); Under voltage warning; Voltage imbalance warning","lifecycle_stage":"current","Run Signal Relay":"Yes","Product Main Type":"PSTX37","Tightening Torque":"Main Circuit 8 N·m","Fault Signal Relay":"Yes","Overload Protection":"Built-in electronic overload protection","Protection Function":"Bypass open protection; Current imbalance protection; Current underload protection; Dual overload (separate overload for start and run); Earth fault protection / ground fault protection; Electronic overload protection, EOL; Extension IO failure protection; Fieldbus failure protection; HMI failure protection; Locked rotor protection; Max number of starts/hour; Over voltage protection; Phase reversal protection; Power factor underload protection; PT-100 connection; PTC connection; Too long current limit protection; Too long start time protection; Under voltage protection; User defined protection; Voltage imbalance protection","Rated Frequency (f)":"50/60 Hz","By-pass Signal Relay":"Yes","Degree of Protection":"acc. to IEC 60529, IEC 60947-1, EN 60529 Main Terminals IP00","Overload Signal Relay":"Yes","Current Limit Function":"1.5 ... 7.5 xle","Ambient Air Temperature":"Operation -25 ... +60 °C","Material Compliance/SCIP":"46ee42b5-0784-4f84-a200-fba43f921301 China","Rated Operational Voltage":"208 ... 690 V AC","Service Factor Percentage":"100 %","Object Classification Code":"Q","Initial Voltage During Start":"10 ... 99 %","Popular Downloads/EPLAN Data":"9AAC181160_EPLAN","Signal Indication Fault (LED)":"Red","Integrated Electronic Overload":"Yes","Step Down Voltage Special Ramp":"100 ... 10 %","Connecting Capacity Main Circuit":"Hole Diameter 8.5 mm","Material Compliance/WEEE Category":"5.
