• Power Supplies: RS‑091, RS‑091/A (24 V DC)KEBA

• I/O Modules: SC‑102, PD‑242/A backplaneKEBA

6. Installation & Wiring

1. Disconnect 24 V DC before installation.

2. Mount module on DIN rail or secure to chassis.

3. Connect +24 V DC and 0 V (GND) to coil terminals.

4. For noise suppression: Wire in parallel with inductive load (relay coil, motor).

5. Keep high‑power wiring separated from signal cables.

6. Power on; check for overheating or abnormal noise.

7. Safety Instructions

• Install and service only by qualified electrical technicians.

• Do not open or modify the module; this voids warranty and risks electric shock.

• Operate only within 24 V DC, ≤25 A rated range.

• Ensure adequate ventilation; avoid covering or enclosing tightly.

• Replace if damaged, overheated, or if insulation fails.

8. Certifications

• CE (EN 61000‑6‑2, EN 61000‑6‑4)

• RoHS compliant
