Common FAQ
How does the 4351B differ from the 4353 model?
The 4351B provides a balanced mix of 10/100 Mbps copper and fiber connectivity, whereas the 4353 is specifically optimized for 100 Mbps fixed-rate environments and includes an embedded OPC server.
What is the primary function of the 500 VDC isolation?
This isolation ensures that transient electrical surges from external network equipment do not propagate to the Tricon backplane, preserving the integrity of the safety processors.
