The exact matching records identify the ISSB-15/15-10, R8792, I2G5, YC9L-1102-10A, YC9L-1103-10A and BDR-34 markings. Weight varies slightly between listings, so approximately 5.1 kg is the safer reference value.
🔌 Operating Function
The ISSB-15/15-10 should be treated as a rack-level component rather than a generic PLC I/O module.
Its “Sol. Barrier Unit Rack” designation indicates that it is intended to organize or interface solenoid-related barrier/control circuitry within the associated Yuken system. The actual signal paths and electrical function depend on the modules installed in or connected to the rack.
For replacement work, the following should be matched carefully:
- ISSB-15/15-10 model number
- R8792 manufacturing number
- YC9L-1102-10A / YC9L-1103-10A configuration
- I2G5 grade
- BDR-34 marking
- Connector arrangement
- Existing wiring
- System voltage and solenoid specifications
Do not assume that another Yuken rack with a similar physical appearance is electrically interchangeable.
🛠️ Installation & Maintenance
Before installation, isolate the associated equipment and confirm that no control or solenoid circuit remains energized.
Check the rack for damaged connectors, bent terminals, corrosion, cracked insulation, loose hardware, and contamination.
For a replacement unit, compare the original and replacement side by side. Pay particular attention to terminal positions and identification labels because legacy Yuken systems may use configuration-specific wiring.
After installation:
- Verify rack orientation and mechanical mounting.
- Confirm every connector is correctly seated.
- Check wiring against the original system documentation.
- Verify supply and control voltages.
- Check solenoid circuits for abnormal resistance or short circuits.
- Power the system according to the manufacturer’s commissioning procedure.
- Test each connected control function individually.
For a used spare, visual inspection and electrical testing before installation are recommended.
🔍 Maintenance Tips
Keep the rack clean and dry, especially around terminal and connector areas.
Avoid applying excessive force to older connectors. Plastic components and cable insulation can become brittle after long service.
When storing the unit as a spare, use anti-static packaging and protect the connectors from moisture and dust.
It is also useful to photograph all connector positions and nameplate markings before removing the original unit. This creates a simple reference for future maintenance.
❓ Frequently Asked Questions
Q: What is the ISSB-15/15-10?
A: It is a YUKEN KOGYO Solenoid Barrier Unit Rack used as a rack-level component in an associated control system.
Q: What is the manufacturing number?
A: Matching records identify the MFG No. as R8792.
Q: What other model numbers are associated with this unit?
A: YC9L-1102-10A and YC9L-1103-10A are listed as additional model details.
