Advanced Display Points
Create custom screens showing metering values, special
text messages, or a mix of analog and status information.
Figure 29 shows an example of how you can use display
points to show circuit breaker information and current
metering. You can create as many as 96 display points.
All display points occupy only one line on the display at
all times. The height of the line is programmable as either
single or double, as shown in Figure 29. These screens
become part of the autoscrolling display when the front
panel times out.
Control Inputs and Outputs
The SEL-411L includes positions for as many as three I/O
boards. You can select these in the following configurations:
➤ Eight optoisolated, independent level-sensitive
inputs; 13 standard Form A and two standard
Form C contact outputs
➤ Eight optoisolated, independent level-sensitive
inputs; 13 high-current interrupting Form A
outputs and two Standard Form C contact outputs
➤ Twenty-four optoisolated, independent level-
sensitive inputs; six high-speed, high-current
interrupting, polarity dependent Form A contact
outputs and two standard Form A outputs
➤ Twenty-four optoisolated, independent level-
sensitive inputs; eight standard Form A outputs
➤ Twenty-four optoisolated, independent level-sensitive
inputs; eight high-speed, high-current interrupting,
polarity dependent Form A contact outputs
Assign the control inputs for control functions, monitor-
ing logic, and general indication. You can use SEL
OGIC
control equations to program each control output. You
can add one I/O board to the 4U chassis, two I/O boards
to the 5U chassis, three I/O boards to the 6U chassis, and
four I/O boards to the 7U chassis. All control inputs are
optoisolated.
