Multifunction Protection for Industrial Motors
The REM610 is a compact and intelligent motor protection relay designed for reliable performance in various industrial environments. It protects medium-voltage motors during startup, running, and shutdown. With a clear LCD display and simple interface, it ensures quick setup and easy local or remote control.
Key Protection Functions
- Three-phase motor startup supervision using thermal stress calculation
- Overcurrent and short-circuit protection with adjustable delay
- Earth-fault and undercurrent (loss of load) protection
- Thermal overload and phase unbalance detection
- Phase reversal monitoring
- Breaker failure protection and restart inhibit logic
- Temperature monitoring with RTD/PTC sensor support
- Emergency start feature for critical scenarios
Inputs & Outputs
- 4 precise current inputs
- 3 digital inputs (expandable with RTD module)
- 3 power output contacts + 2 configurable signal outputs
- Digital time-sync input for system coordination
Built-in Disturbance Recorder
The REM610 includes a recorder that logs up to 80 seconds of data from 4 analog and 8 digital channels, supporting both internal and digital trigger inputs. Adjustable sampling ensures accurate diagnostics.
User-Friendly HMI
- Alphanumeric backlit LCD screen
- 8 programmable status LEDs
- Easy navigation with password-protected access
- Multi-language support
Communication Options
- Front optical port for local access
- Rear port with support for Modbus, IEC 60870-5-103, or SPA-bus
- Battery-backed real-time clock for reliable logging
Applications
Ideal for motors in pumps, fans, mills, crushers, and conveyor systems. The REM610 supports both circuit breaker and contactor-controlled drives and also offers feeder and transformer protection.
