Output Power - indicates power is
being received from field termination board
from the external power supply for binary
outputs and isolated binary inputs.
Protection
The InterOP8500 module is protected by
internal solid state Polyswitches on the
incoming power and network connections.
These Polyswitches are not replaceable and
will reset themselves if the condition that
caused the fault returns to normal.
Production Date
To determine when a module was
manufactured, check the module status
report for the module in WebCTRL or
SuperVision. Refer to the appropriate user’s
guide for more information about the module
status report.
A sticker on the back of the module also
shows the date the module was
manufactured. The first three characters on
the sticker indicate the type of module. The
next two characters show the year and month
of manufacture.
