SEL-2241 Real-Time Automation
Controller (RTAC)
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 stand-alone RTAC modules, but is mounted in and receives power
from the Axion backplane.

The following figure shows the RTAC status LEDs that
aid system troubleshooting and the connectors for
communications and wiring.

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
(shown in Figure 2) with Slot A of the chassis, and place
the module on the bottom lip of the chassis as Figure 3
illustrates. The module is aligned properly when it rests
entirely on the lip of the chassis.
