71M6403 Electronic Trip Unit The Teridian 71M6403 is an electronic trip unit ETU system-on-chip device for air circuit breakers ACB , molded case circuit breakers MCCB and other types of intelligent switchgear. Utilizing Teridian’s patented Single Converter Technology , the 71M6403 incorporates a 22-bit delta-sigma ADC, 7 current sensor inputs, digital temperature compensation, precision voltage reference, 32-bit programmable computation engine, timers, Real Time Clock RTC , two UARTs and an single cycle execution 8-bit MCU. Armed with an internal digital di/dt integrator, this programmable device supports either current transformer CT or Rogowski-Coils for any or all input channels and provides instantaneous and delayed over current, earth-leakage, ground-fault and arc fault protection functions. Furthermore, the device may be configured to support any number of conventional or custom protection algorithms that fit specific load configurations in the field. The 71M6403 includes a 5V LCD charge pump as well as 3V LCD support with up to 168 pixels display and up to 22 DIO pins. Easy conversion to ROM offers unprecedented cost structure for high volume MCCB applications. A complete suite of in-circuit emulator ICE and development tools, a powerful realtime signal monitoring tool, programming libraries and reference designs enable rapid development of advanced switchgear.
