A three-phase motor protection and control relay designed for the LV motor protection market is available from NewElec. NewCode provides comprehensive motor protection with time and date stamped event and fault records, as well as integrated user-configurable control logic functions and standard starter control blocks.
For maintenance engineers, the relay records the last 1660 events as well as the last 40 faults, together with details such as current interrupted, minimum voltage present at the time, rapidity of circuit interruption and the time and date of occurrence. Setting alterations are also recorded. The front-end data recorder and spectrum analyser can be used to monitor motor performance or to detect harmonics up to the 9th harmonic of any three-phase current.
In addition to basic motor protection requirements NewCode offers Profibus, Modbus and Canbus communications protocols, making the relay an ideal solution for plant protection and automation. NewCode is ISO 9001:2000 compliant. Other features include LED indications for all faults as well as I/O status; control panel mounted LEDs that continuously emit the relay address; a USB port; and an infrared data acquisition port. The free support software includes a recording utility, a calculator and a fully functional simulator that is adaptable for manual or automatic data inputs and is ideal for training centres.
