Relay Contact
The Ethernet switch has one Relay Contact located on the top panel.
For detailed instructions on how to connect the Relay Contact power
wires to the two middle contacts of the 6-contact terminal block
connector, see the
Wiring the Relay Contact
section. A typical
scenario would be to connect the fault circuit to a warning light located
in the control room. The light can be set up to switch on when a fault is
detected.
The Relay Contact has two terminals that form a fault circuit for
connecting to an alarm system. The two wires attached to the fault
contacts form an open circuit when (1) a relay warning event is
triggered, (2) the switch is the Master of this Turbo Ring, and the Turbo
Ring is broken, or (3) start-up failure. If none of these three conditions
occur, the fault circuit will be closed.
Turbo Ring DIP Switch Settings
IE-SW-VL05/08M models are managed Ethernet switches that offer
redundancy. The proprietary Turbo Ring protocol provides better
network reliability and faster recovery time. Turbo Ring’s recovery time
is less than 300 ms (
Turbo Ring
) or 20 ms (
Turbo Ring V2
) -
compared to a 3- to 5-minute recovery time for commercial switches -
decreasing the possible loss caused by network failures in an industrial
setting.
There are 4 Hardware DIP Switches for Turbo Ring on the top panel of
IE-SW-VL05/08M series that can help setup the Turbo Ring easily
within seconds. If you do not want to use a hardware DIP switch to
setup the Turbo Ring, you can use a web browser, telnet, or console to
disable this function.
NOTE
Please refer to the
Turbo Ring DIP Switch

section in User’s
Manual for more detailed information about the settings and
usage of
Turbo Ring
and
Turbo Ring V2
