Smart circuit breaker
E-T-A Circuit Breakers has introduced the E-l 048-800 smart circuit
breaker. Designed with solid state technology to provide relay control,
the unit is said to be the first device of its kind to combine
solid-state switching, electronic circuit protection, analog signal
output and diagnostic functions.
The unit√É¬≠s power controller is suitable for switching dc loads in automotive and automation applications, and for low voltage dc or multiplex control systems used in power circuits on boats and other vehicles. The 0 to 5 V analog output is proportional to the current flowing through the device. If this output is connected to a PLC or ASIC microcontroller, the signal can be used to provide intelligent relay control.
