Installation Guide

Safety Precautions

• De-energize the Ovation rack before installation
• Use proper ESD protection when handling the module
• Verify field device signal type and range before wiring

Step-by-Step Procedure

1. Power down the Ovation I/O rack
2. Align the module with the rack slot and insert firmly
3. Secure the module retaining clips
4. Connect analog field wiring to the terminal base unit
5. Power up and verify module status LEDs
6. Calibrate input channels via Ovation engineering station

Selection Tips

• Verify channel count (8 vs 16) with your supplier before ordering
• For HART smart transmitter communication, select 5X00058G01 or 5X00106G01 instead
• For high-speed sampling (>100 Hz), consider 5X00070G01
• Ensure input signal range matches field transmitter output (4-20mA, 0-10V, etc.)
