Product Introduction
ABB UAD206A101 3BHE019958R0101 serves as a discrete output interface for Bailey INFI 90 control systems. It drives solenoids, relays, and indicator lamps from the internal controller bus.Field units typically handle 16 independent loads at 24V DC with 0.5A switching capacity. The module includes short-circuit protection and open-load detection to prevent downstream wiring faults from disabling the entire card.
Installation & Configuration Guide
Preparation (10 min)
- Verify power is OFF at the main disconnect.
- Confirm 24V DC supply capacity includes a 20% margin for this module.
- Gather insulated screwdrivers and wire strippers.
Removal (5–10 min)
- Label all field wires before disconnecting.
- Release the DIN rail latch or remove panel screws.
- Slide the module out of the backplane connector.
- Inspect backplane pins for corrosion or bending.
Installation (10 min)
- Align the module with the backplane guide rails.
- Press firmly until the connector seats fully.
- Engage the DIN rail latch or secure panel screws.
- Reconnect field wires to the correct terminals.
Power-On & Test (10 min)
- Restore 24V DC power to the rack.
- Check the green “OK” LED on the module face.
- Force a single output ON via the controller.
- Measure 24V DC at the terminal with a multimeter.
- Clear the force and verify the LED extinguishes.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Immediate Action |
|---|---|---|
| No LEDs lit | No backplane power | Check 5V/24V rack supply fuses |
| Red Fault LED | Short circuit on output | Disconnect field wires; measure resistance |
| Output won’t turn ON | Blown internal fuse | Replace module; verify load <0.5A |
| Intermittent signals | Loose backplane connection | Reseat module; inspect connector pins |
| All outputs stuck ON | Internal logic failure | Power cycle rack; replace if persistent |

FAQ
Will this work with my older INFI 90 rack?
Yes, but check the backplane revision first. Some early racks require a firmware patch for newer output modules.I need to replace a failed card today. Is it in stock?
We keep tested units ready to ship. Lead time is typically 1–2 business days for domestic orders.Can I use this for high-current solenoids?
No. The 0.5A limit is hard. Use an external relay for loads above that threshold.Is this module refurbished or new surplus?
Most units are refurbished and tested. We clearly label condition on every listing.Do I need to configure DIP switches?
No. UAD206A101 is auto-configured by the controller. Just ensure the slot address matches your logic.What if the LED flickers?
That usually means marginal 24V supply or a loose wire. Check voltage under load with a meter.Can I mix this with third-party I/O?
Technically yes, but stick to ABB modules for guaranteed backplane compatibility and diagnostics.
