GDD471A001 2UBA002322R0001 ABB Control Board

GDD471A001 2UBA002322R0001 Control Function with 24 V DC ≥ 10 mA PLC Output:

• Built-in PLC Interface:
  • GDD471A001 2UBA002322R0001 Operates the AF contactor coil with voltage range:
    • 100 … 250 V AC / DC
    • 250 … 500 V AC / DC
  • Suitable for AF contactors:
    • From 55 kW – 400 V / 75 hp up to 560 kW – 400 V / 900 hp 480 V
    • Up to 2850 A AC-1 / General use
  • Dedicated coil code from AF116 up to AF370
  • Standard feature from AF400 up to AF2850
• Function Description:
  • Control signal:
    • “1” represents 24 V DC between control signal and COM
    • “0” represents no voltage between control signal and COM
  • ON and OFF_N can be connected in parallel for a common ON/OFF signal
  • GDD471A001 2UBA002322R0001 Function includes voltage supply limits:
    • Closing at 77%
    • Opening at 55%
• Protective Separation:
  • Ensures safe isolation of circuits to prevent voltage transfer in case of single failures
  • Requirements comply with IEC / EN 60947-1, Annex N
  • Basic requirements include double or reinforced insulation, protective shield, or combination of both
  • Insulation must resist aging throughout expected lifetime
  • No safe separation required for circuits without safety extra-low voltage or functional extra-low voltage
• Mechanically Linked Contacts or Mirror Contacts:
  • Defined according to IEC / EN 60947-5-1, Annex L
  • Combination of Make and Break auxiliary contact elements designed to prevent simultaneous closed position
  • Control circuit devices may have multiple groups of mechanically linked contact elements
  • ABB contactor relays undergo testing in accordance with IEC 60947-5-1 and feature positively driven contact elements in basic units or in conjunction with auxiliary switches since product introduction.
