Product Introduction
ABB 758108 is a Syscon 3 complete circuit board used in the URAS 26 central electronic unit. ABB’s own listing describes it as “Circuit board, syscon 3 complete,” and related product data shows a replacement product ID of 758108P.
This is a legacy ABB control board, so exact revision matching matters more than appearance. Verify the replacement ID, memory version, and unit compatibility before ordering, because a similar-looking board may not boot in the same cabinet.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Board will not power up | Supply fault or failed board | ✅ High | Measure input supply and check status LEDs | Verify cabinet power first |
| Unit boots but alarms immediately | Revision or memory mismatch | ✅ High | Compare part number, replacement ID, and memory spec | Match the exact ABB replacement code |
| Data or control loss | Corrupted configuration or board fault | ✅ High | Check logs and reload known-good configuration | Restore configuration before replacing hardware |
| Intermittent operation | Loose connector or aging board | ✅ High | Reseat connectors and inspect for bent pins | Test continuity and contact integrity |
| Wrong readings from field device | External sensor or wiring issue | ⚠️ Medium | Verify input wiring at the field terminals | Do not condemn the board until inputs are checked |
| Communication failure with host | Protocol or interface mismatch | ✅ High | Confirm the host interface settings and cable type | Check the upstream system and cabling |
If you are stuck, contact technical support with photos, fault logs, and the exact label from the removed board.
