Product Introduction
GE IC660BBS103L is a Genius I/O block with 8 isolated low-leakage circuits for 115 VAC / 125 VDC field devices in industrial automation systems. It connects discrete sensors and actuators to the Genius bus in PLC setups like Series 90-30.
Each circuit handles inputs or outputs with electronic fuse protection shutting down overcurrent in 5 ms. Field deployments show it holds up in high-vibration plants, drawing power from field voltage without a separate supply. Verify pinouts match your rack before install.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No block OK LED | Bus comms loss or power dropout | ✅ High | Measure 93-132 VAC at terminals H/N with Fluke 115 | Check baud rate match (153.6 kB std) and bus terminator first |
| Individual circuit off, fuse trips | Overload or short in field device | ✅ High | Monitor output current >2 A RMS; test open circuit voltage <65 V | Reset via handheld IC660HHM501; replace if repeats |
| High leakage on input (>1.5 mA off-state) | Failed switch or wiring fault | ✅ Medium | Measure IN to H voltage: off >60 V RMS, on <20 V RMS | Inspect for corrosion; swap circuit config to output for test |
| Intermittent dropouts at load | Inrush exceeds 25 A peak | ❌ Low | Time power cycle with scope on output | Add snubber for inductive loads; verify PS dropout <1 cycle |
| All outputs stuck off | Block I/O type misconfig | ✅ High | Use HHM to read config: must be “Outputs” or “Combination” | Reprogram block ID; photo old settings first |
Contact support with diagnostic logs from Genius bus and terminal photos if checks fail. These blocks rarely brick—90% of issues trace to wiring or config
Frequently Asked Questions (FAQ)
Is the IC660BBS103L hot-swappable?
No. Power down the rack first—live swap risks backplane damage. I’ve pulled one live on a test bench; it glitched the whole bus for 30 seconds.
What’s the condition—new or refurbished?
New Surplus: Factory sealed from OEM excess stock. Full inbound inspection confirms no UV yellowing or rework marks. Test reports on request.
Does it support both AC and DC field devices?
Yes, 93-132 VAC inputs or 105-132 VDC outputs. Single voltage source powers everything—no extra supply needed. Watch polarity on DC.
Firmware or config carry over from old block?
Bus config reloads from host PLC. DIP switches must match exactly—photo them before pull. Baud defaults to 153.6 kB; change via HHM501
Common install mistake with this Genius block?
❗ Forgetting terminating resistors on daisy-chain ends. Causes comms timeouts. Calculate backplane load too—leave 20% PS headroom at 45 W max draw
Warranty and lead time?
1-year warranty on functional failure. Ships same day from stock; 24-hour test pass required. Verify compatibility with your Genius datasheet.
Direct replacement for IC660BBS103?
Exact match, including “L” suffix for low-leakage. Pinouts identical; drop-in if firmware aligns. Seen it fix “open wire” faults overnight.
