- Manufacturing Automation: Synchronizes production line controllers, robotic systems, and quality inspection stations for coordinated operations
Solution Benefits
Enhanced System Reliability: Centralized time distribution eliminates clock drift across networked controllers, preventing timing conflicts and ensuring deterministic system behavior.
Simplified Troubleshooting: Accurate SOE recording with synchronized timestamps enables rapid root-cause analysis of process upsets, equipment failures, and alarm cascades.
Regulatory Compliance: Meets stringent time-stamping requirements for FDA 21 CFR Part 11, ISO 9001, and industry-specific audit trail documentation standards.
Scalable Architecture: Supports multiple time distribution protocols, allowing seamless integration with legacy systems and future technology upgrades.
Common Questions
Q: Can the SPTKM01 synchronize with external GPS time sources?
A: Yes, the module accepts GPS-disciplined clock inputs via IRIG-B or NTP protocols, ensuring UTC-traceable time accuracy across your entire control system.
Q: How many slave devices can one SPTKM01 master support?
A: The master unit can distribute time signals to up to 64 slave time keeper modules or compatible controllers within the same network segment, depending on communication infrastructure.
Q: Is hot-swapping supported for maintenance?
A: The SPTKM01 supports online replacement when configured with redundant master units, minimizing system downtime during scheduled maintenance activities.
Q: What happens if the master time source fails?
A: The module features internal holdover capability, maintaining accurate timekeeping for up to 24 hours using its onboard oscillator until the primary time reference is restored.
