Greutate: 0.294 kg

Certificari: CE, cULus, FM

Conexiune: Side expansion cable directly connected to LOGO! unitate principală, no separate communication cable required

📌 Compatibility (Notă critică)

✅ Compatible Main Units: LOGO!8 / LOGO!8.2 (order number suffix 0BA2, 0BA3, etc.)

❌ Not compatible with older LOGO! 0BA6 / 0BA7 (different hardware interface; program incompatible)

Multiple DM modules can be expanded on one LOGO! unitate principală, limited by the total I/O capacity of the controller.

🧰 Typical Application Scenarios

1. Electrical cabinet, HVAC, pompa de apa & fan control: Collect 220V limit switches and pressure switches; directly drive 220V contactors, solenoid valves and indicator lamps.
2. Transportor mic & packaging stand-alone machines: Expand I/O points when the main unit runs out of capacity for AC signal circuits.
3. Automatizarea clădirilor, ventilation and roller shutter control (AC signal loops).
4. Proiecte de modernizare: Existing 220V sensors and actuators without adding intermediate relay isolation.

Selection Reminder: This module is 230V voltage class. For DC24V signals, choose DM16 24R (6ED1055-1NB10-0BA2).

⚠️ Troubleshooting & Ghid de operare

1. Module no response: Check if the side expansion cable is fully latched; the module itself requires AC/DC230V power supply independent of the main unit.
2. Input channel not detected: Input voltage must exceed the 79V threshold; low voltage signals cannot trigger the input; distinguish AC/DC signal types strictly.
3. Damaged relay outputs: Relay contacts are easily damaged by back EMF from inductive loads (bobine de contactor, electrovalve). Install RC snubber circuits in parallel with coils to extend contact life.
4. Load limit: Max 5A per channel; avoid long-term full-load operation on all 8 channels simultaneously to prevent overheating.
5. Passive relay output: No built-in common power on contacts; load power must be wired externally.
