industrial protocols such as Modbus and Profibus, the terminals can easily be inte­grated into various control systems.

The machine terminal measures three-phase currents and voltages via conven­tional current and voltage transformers. If preferred, the three-phase currents can be measured via highly linear current sensors of type Rogowski coils. Correspondingly, the three-phase voltages can be measured via sensors of type voltage dividers. Further, the terminals can be fitted with an optional I/O module featuring eight general use RTD/analog signal inputs and four analog mA outputs. The inputs can be used for measuring the winding, bearing or cooling air temperatures of the machine as well as the ambient temperature. The freely assign­able analog mA outputs can be used to transfer measured or calculated values to

additional panel meters, co-operating au­tomation systems, PLCs or the like.

The relay is provided with a sophisticated local Human-Machine Interface to facilitate extensive local communication between the operator and the terminal. The back-lit, graphic liquid crystal display has a resolution of 128 x 160 pixels. The large display surface is divided into two windows for display of alpha-numerical data, such as settings, measured and recorded values, alarms, etc as well as graphics like single­line diagrams of the switchgear lay-out. The informative display, the local control push-buttons and indicators give the op­erator full control of the terminal during start-up, operation and disturbance situa­tions of the protected machine.

REM 543/545 motor and generator ter­minals are part of ABB's substation au­tomation concept and the RE500 series. Innovative solutions like IEC 61850 sup­port and the simultaneous dual port communication offering flexible connec­tivity cater for all your communications needs and help to cover future demands.

Their common configuration, setting and monitoring tools offer you yet another benefit: you only need to learn how to use one of our products, because all of our RE500 series protection relays and monitoring and control terminals use the same technology.
