Product Description
Ready-to-Rack Summary
- Part Number: 6ES7322-5GH00-0AB0 (Hybrid 8 Relay + 8 Transistor Outputs)
- Condition: Factory New Sealed in Original Siemens Packaging
- Warranty: 24 months (with full hybrid load test report)
- Availability: 24-hour worldwide dispatch from EU/US stock
- Configuration: 8 potential-free relays (5 A) + 8 transistor outputs 24 V DC / 0.5 A
The Perfect Mixed-Load Card for S7-300 Retrofits in 2025
One slot, two output types – the ultimate space-saver when you need both high-power AC/DC relays and fast low-power DC switching in the same rack. Plants keep it on the shelf because:
- Solves “need one more relay but no slot left” problems instantly
- 8 relays for motors/valves + 8 fast transistors for pilot lights and proximity flags
- Single front connector (40-pin) – no extra wiring complexity
- Fully supported in STEP 7 V5.7 and TIA Portal 18
Failure Symptoms Driving Immediate Replacement
Maintenance teams order this exact hybrid card when:
- “Relay channels 1–4 no longer switch” or “transistor group overload 16#E500”
- Mixed diagnostic faults: relay stuck closed + transistor short-to-ground
- LED mismatch: relay LED ON but contact open
- Hot-swap fails due to mixed output type confusion
Real-World Deployments 2024–2025
- Machine Building: Krones bottling lines – relays for pneumatic valves, transistors for sensor LEDs
- Wastewater: Siemens SITRANS systems – relays for pump starters, transistors for status signals
- Test Stands: Automotive OEMs – hybrid control of actuators and indicator towers
