The SEL-2244 provides contact input and outputs for the SEL Axion' . Within an Axion node, install any combination Front Panel Mechanical Installation Figure 1 SEL-2244 Digital Input and Output Modules Each SEL-2242 chassis/backplane has ten slots, labeled A through J. Slots B^J support the SEL-2244 Digital Input and Digital Output modules. Figure 2 Notch for Module Alignment To install an SEL-2244 module, tip the top of the module away from the chassis, align the notch on the bottom of the module (shown in Figure 2) with the slot you want on 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. Schweitzer Engineering Laboratories, Inc.

EtherCAT® portion in the Section 2: Communications in the ACSELERATOR RTAC SEL-5033 Instruction Manual for details. NOTE: Ensure that when you are applying ac power to inputs with common returns that ac neutral is connected to the common terminal. Digital Inputs Proper Module Placement Next, carefully rotate the module into the chassis, making sure that the alignment tab fits into the corresponding slot at the top of the chassis (refer to Figure 4). Finally, press the module firmly into the chassis and tighten the chassis retaining screw. Refer to the Specifications on page 3 for output contact...
