Schweitzer Engineering Laboratories, Inc. SEL-2241 Data Sheet
Each SEL Axion
®
system requires an RTAC module to serve as the system CPU. The SEL-2241 RTAC has all of the
communications and custom logic capabilities of the standalone RTAC modules, but is mounted in and receives power
from the Axion backplane.
Front-Panel
The following figure shows the RTAC status LEDs that
aid system troubleshooting and the connectors for com-
munications and wiring.

Mechanical Installation
Each SEL-2242 chassis/backplane has ten slots, labeled
A
through
J
. Only Slot
A
supports the SEL-2241 RTAC
module.
To install the RTAC, tip the top of the module away from
the chassis, align the notch on the bottom of the module
with Slot
A
of the chassis, and place the module on the
bottom lip of the chassis as Figure 2 illustrates. The
module is aligned properly when it rests entirely on the
lip of the chassis.
Figure 2 Proper Module Placement
Next, carefully rotate the module into the chassis, mak-
ing sure that the alignment pin fits into the corresponding
slot at the top of the chassis (refer to
Figure 3 ). Finally,
press the module firmly into the chassis and tighten the
chassis retaining screw.
