Product Description
Ready-to-Rack Summary
- Part Number: 6ES7322-8BF00-0AB0 (8-Channel High-Current Transistor Output)
- Condition: Factory New Sealed in Original Siemens Packaging
- Warranty: 24 months (with full 2 A load test certificate)
- Availability: 24-hour worldwide dispatch from EU/US stock
- Channels: 8 individually isolated, 24 V DC / 2 A per channel (total 8 A)
The Go-To High-Power DC Output Card for S7-300 in 2025
When standard 0.5 A outputs can’t handle big solenoids, heating elements, or brake coils, this 2 A-per-channel module is the proven drop-in solution. Plants stock it because:
- Full 2 A continuous per channel – no derating even at 60 °C
- True isolation between channels – safe for mixed loads and diagnostics
- Short-circuit proof with electronic trip + automatic restart
- Still fully supported in TIA Portal 18 and STEP 7 V5.7
Failure Symptoms Triggering Immediate Orders
Technicians rush-order this card when:
- “Channel overload 16#E600” or single channel stuck OFF after overcurrent
- 2 A solenoid or brake coil no longer activates (measured <18 V at load)
- Group fault LED red + diagnostic buffer “output short-circuit to M”
- Existing 0.5 A card repeatedly trips on startup current
Real-World Deployments 2024–2025
- Robotics: KUKA & Fanuc cells – direct brake release and gripper solenoids
- Presses: Schuler lines – hydraulic valve coils and safety brakes
- Cranes: Demag & Konecranes – 24 V magnet & hoist brake control
