JB660B Microcomputer-based Relay Protection Device

Home / JB660B Microcomputer-based Relay Protection Device

The microcomputer relay protection device has the advantages that as the serial buses are adopted instead of special connecting lines and parallel buses, the connecting lines for the backplanes are reduced, the flexibility and reliability are enhanced and the complexity of the. On the basis of a design mode of backplanes and plug-in boards, the microcomputer relay protection device mainly comprises a master processor plug-in board, an on-off input plug-in board, a relay. The HZJB-660T is designed to test various relays (such as current,voltage,inverse time,power direction,impedance,differential,low frequency,synchronization,frequency,DC,intermediate,time relays,etc.
