Numerical Relay ABB

REM601 is a dedicated motor relay designed for the protection and control of medium-voltage and low-voltage asynchronous motors in the manufacturing and process industry. The relay provides an optimized composition of protection, monitoring and control functionality in one unit, with the best performance usability in its class.

The relay’s stand­ard signal configuration can be altered from its local user interface (LHMI). The relay can be used with both circuit-breaker and contactor-controlled motor drives.

Besides the conventional current transformer interface based variant, the relay also supports a variant based on Rogowski current sensors’ analog interface. This helps to obtain a compact medium voltage switchgear equipment size reduc­tion with improved performance and standardization.

ABB Numerical relays

ABB Numerical relays are based on the use of microprocessors. A big difference between conventional electromechanical and static relays is how the relays are wired. Electromechanical and static relays have fixed wiring and the setting is manual. Numeric relays, on the other hand, are programmable relays where the characteristics and behavior can be programmed. Most numerical relays are also multifunctional.

Scope
