Product Details
The RJ-45 connectors support multiple insertions and removals with an estimated service life expectancy of 200 insertion/removal cycles. Connector components are exposed to torsion forces across any axis of the connector and tension forces that are static from cable weight and cable dressing. Dynamic stresses are imposed on the connectors from transients in assembled system transport to the plant site and operation in a high vibration power production environment. Connector design anticipated static forces of three pounds force (89.9 Newton) per connection while complying with the other dynamic operating load requirements.
The performance of a level 1 Ethernet switch is mainly centered on the ability to buffer packets. When a level 1 switch has a continuous stream of incoming broadcast or multicast packets, the switch must in turn send those packets out upon complete reception. A single incoming stream should require enough space to buffer one packet or at the most one packet per port.When the switch has multiple incoming streams, it is only able to relieve one of the incoming streams and must buffer the rest for later transmission.
Installation：
For new installations, mount the switch or switches onto the control system panel(s) using a DIN-rail. Connect the copper
and/or fiber cables in accordance with system requirements and redundancy. Connect the 28 V dc power from the power
distribution board to the switch.
When the ESWA or ESWB is used to replace a different unmanaged switch, it uses the existing mounting brackets, which can either be panel or DIN-rail mounts. There are seven screw holes used on the existing switch to support panel mounting.
The ESWx switch is available in the following form factors:
