4. Application Fields & Cases

4.1 Application Fields

• Industrial Robotics: Emergency stop monitoring for robot cells, safety gate interlocks
• Manufacturing: Light curtain control, two-hand control stations, conveyor safety interlocks
• Packaging: Machine guarding for filling/sealing equipment, palletizer safety circuits
• Automotive: Welding cell safety systems, assembly line emergency stop circuits
• Food & Beverage: Safety interlocks for processing machinery, packaging line guarding

4.2 Typical Cases

1. Robotic Welding Cell Safety: An automotive OEM installed YASKAWA JGSM-12-11-S in robotic welding cells to monitor emergency stop buttons and safety gates. The module’s dual-channel inputs detected a broken emergency stop wire, triggering an immediate machine shutdown and preventing a potential operator injury.
2. Packaging Line Guarding: A food packaging facility used YASKAWA JGSM-12-11-S to interlock safety gates with a high-speed filling line. When a gate was opened during operation, the module shut down the line within 40 ms, avoiding product spillage and operator exposure to moving parts.
3. Conveyor System Safety: A logistics provider integrated YASKAWA JGSM-12-11-S into conveyor systems to monitor light curtains at loading/unloading stations. The module’s diagnostic LEDs identified a faulty light curtain sensor, allowing maintenance to replace it before a safety incident occurred.

6. Selection Suggestions & Precautions

6.1 Selection Suggestions

1. Safety Requirement Matching: YASKAWA JGSM-12-11-S (Cat 4/PL e/SIL 3) is ideal for high-risk applications (e.g., robotic cells, heavy machinery); for lower-risk tasks (e.g., small conveyors), select Yaskawa JGSM-08-11-S (Cat 3/PL d).
2. Input/Output Needs: Verify the number of safety inputs/outputs required (4 inputs/3 outputs for YASKAWA JGSM-12-11-S); choose modules with additional channels for complex safety circuits (e.g., multiple emergency stops).
3. Environmental Conditions: Select YASKAWA JGSM-12-11-S for cold-temperature environments (-25°C to +55°C); use enclosed versions for dusty or humid locations (e.g., food processing plants).

6.2 Precautions

1. Wiring Guidelines: Use shielded cables for safety inputs/outputs, with shielding grounded at one end only to avoid ground loops. Wire dual-channel inputs separately to prevent common-mode faults.
2. Installation Compliance: Mount YASKAWA JGSM-12-11-S in a dedicated safety circuit section of the control panel, away from high-voltage equipment (e.g., contactors) to minimize EMI interference.
3. Maintenance Checks: Inspect output contacts annually for wear (replace if contact resistance exceeds 100 mΩ); test safety circuits monthly to ensure YASKAWA JGSM-12-11-S triggers shutdowns correctly.
4. Fault Handling: Do not bypass safety circuits or disable YASKAWA JGSM-12-11-S diagnostics—address faults immediately to maintain compliance with safety standards and prevent accidents.
