Working Principle

The T3151 module operates as the communication and timing hub within the Regent system. The real-time clock circuit maintains continuous timekeeping using a dedicated oscillator and backup power source. The communication processor manages RS232 data exchange between the Regent controller and external devices. In TMR configurations, three independent T3151 modules operate simultaneously, with their outputs cross-checked to ensure only valid time-stamped data is recorded and transmitted.

Installation Requirements

  • Install in a designated communication slot in the Regent chassis
  • Connect the RS232 cable to the front-panel port using shielded wiring
  • Configure clock settings and time synchronization via system software
  • Ensure proper chassis grounding
  • Verify TMR configuration settings when installing redundant modules

Operating Precautions

  • Verify real-time clock accuracy during system commissioning
  • Maintain backup power for the clock circuit during main power outages
  • Monitor communication status for fault indication
  • Replace failed modules promptly in TMR configurations to restore redundancy
  • Synchronize clocks across all T3151 modules in redundant configurations
  • Follow proper ESD procedures during module handling
