•
Flexible hardware architecture
•
Self-monitoring routines for device faults
General Properties
•
Fully digital measured-value processing and control, from sampling and digitizing of measurands to
closing and tripping decisions for the circuit‑breaker.
•
Complete galvanic and interference-free isolation of the internal processing circuits from the system
measuring, control, and supply circuits through instrument transformers, binary inputs, binary outputs
and DC/AC voltage converters.
•
User friendly operation from the front fascia or from the Reydisp software tool via the data comms ports.
•
Display of measured and metered values at the front.
•
Storage of system demand data measured values.
•
Storage of data relating to system faults with real-time tagging.
•
Storage of instantaneous analogue values for fault records and analysis.
•
Continuous monitoring of the measurands as well as the device hardware and software.
•
Communication with central control and storage devices possible via the device interface.
•
Synchronizable clock
The ordering structure for the devices is very straightforward as the devices have flexible interfaces and
ordering options are minimized
