Core technical parameters
Control power supply: 80-265 VAC/90-300 VDC, 2A max, 50/60Hz or DC; HI annotation corresponds to high voltage control power supply, different from LO (low voltage) version
RTD configuration: 12 programmable 100 Ω platinum resistance (Pt100) inputs, used for stator, bearing, and environmental temperature monitoring
input
5 factory pre programmed digital inputs, 1 programmable analog input
4-channel output relay (1 main trip, 1 alarm, 2 auxiliary, configurable latch/non latch, fail safe)
Communication: RS-485 interface, supporting Modbus RTU; Can be connected to PLC/DCS for remote monitoring
Environment and Machinery
Working/storage temperature: -25 ° C to 60 ° C
Protection level: Panel IP40, overall IP20
Typical dimensions and weight: approximately 203 × 203 × 330mm, approximately 3.5kg
Certification: UL, CE, IEC related electrical safety and electromagnetic compatibility standards

Core functionality
Comprehensive motor protection: overload (8 standard curves+FlexCurve customization), stall/stall, phase failure/phase imbalance, ground fault, overvoltage/undervoltage, reverse phase, thermal overload (I ² t model+RTD dual verification)
Startup management: limit the number of startups per hour, control the startup interval, and monitor the acceleration time
Temperature monitoring: 12 independent RTD alarm/trip thresholds, bearing/winding overheating protection
Event recording and diagnosis: capturing fault waveforms, historical events, and operational statistics for quick problem localization

Typical application scenarios
Widely used in metallurgy, oil and gas, water treatment, power, mining and other industries to protect large three-phase AC motors such as water pumps, fans, compressors, conveyors, machine tool spindles, especially suitable for occasions with strict requirements for motor temperature and starting conditions.
