DIGISOL DG-IS4514E is based on a new generation of high-performance hardware and supports ACL, QinQ and QoS. DG-IS4514E with standard DIN-Rail shell provides wide-voltage dual power input. DG-IS4514E uses highly reliable industrial Ethernet ring network technology. The hardware-based algorithm can ensure that the self-healing time of each node is less than 5 milliseconds, and the self-healing time of the ring network is less than 50 milliseconds (typical value).
