Working Principle Field discrete safety signals connect to FC-TSDI-16UNI screw terminals. Users set configuration jumpers to select sink or source mode matching field device wiring. Signals pass through fuse and surge suppression circuit, then transmit to safety digital input module via SIC ribbon cable. Fuse breaks circuit under overcurrent fault. Surge components suppress transient voltage. Signal and fault information transfers bidirectionally between field devices and safety input module.

Installation Requirements

  • Mount FC-TSDI-16UNI on standard 35mm DIN rail inside control cabinet.
  • Set channel configuration jumpers according to field device sink/source requirement before power on.
  • Use shielded twisted pair cable for field safety device wiring.
  • Tighten terminal screws to specified torque.
  • Connect SIC ribbon cable to corresponding safety digital input module.
  • Separate signal cables from high power cables in cable tray.
  • Complete protective earth connection for assembly housing.
  • Perform continuity and channel function test after wiring completion.

Usage Notes

  • Cut off field loop power before adjusting configuration jumpers or replacing fuses.
  • Replace fuses with same rated specification only.
  • Keep cabinet dry and free of oil mist and conductive dust.
  • Check terminal tightness periodically under vibration condition.
  • Do not modify internal circuit components.
  • Disconnect SIC ribbon cable before insulation resistance test.
  • Replace assembly immediately when permanent circuit damage occurs.
