Installation Guide

1. Insert the module into an X80 rack slot and secure.
2. Connect the 28-pin terminal block.
3. Wire SSI encoders, capture inputs and reflex outputs according to the pinout.
4. Configure channel parameters, baud rate and functions in the programming software.
5. Verify communication and status LEDs after power-up.

Selection Tips

• Use BMXEAE0300 for multi-axis absolute position applications (gates, pitch control, etc.).
• Confirm encoder supply and current capability (minimum 5 mA output recommended).
• Select the H version for severe environmental conditions.
• Ideal for hydro, wind and precise motion control systems.
