Installation Guide

Installing the Schneider Electric 170ADM39030C requires a Momentum base or rack. Follow these steps for a proper setup.

1. Power Down the System: Turn off 24 VDC power to the Momentum station.

2. Mount the Module: Snap the 170ADM39030C onto the DIN rail or backplane.

3. Connect Inputs: Wire field devices to the 10 input terminals.

4. Connect Outputs: Wire loads to the 8 relay output terminals.

5. Wire the Power Supply: Connect 24 VDC to the rated supply terminals.

6. Secure All Wires: Tighten terminal screws to the specified torque.

7. Power Up: Restore 24 VDC and check module status.

Do not exceed the relay contact ratings on the 170ADM39030C. Use external suppression for inductive loads to extend relay life.
