Contact Configuration: 1NO + 1NC
Mounting Type: Side Mount (Left side of starter)
Compatibility: Specifically designed for NS2-80 series motor starters (Referred to as NS2-AU11(NS2-80) in datasheets)
Secure Snap-On Installation
Provides Electrically Isolated Contacts for control circuits
Remote Monitoring: Allows external systems like PLCs or indicator panels to accurately track the ON/OFF status of the NS2-80 motor starter.
Control System Interlocking: Facilitates the implementation of safety protocols or operational sequences based on the starter's state.
Automation Integration: Enables the incorporation of the NS2-80 manual starter into broader automated control schemes.
Versatile Signaling: Offers both NO and NC contacts to suit various control logic requirements.
Model: AUX-NS2-80-AU11 (Corresponds to type NS2-AU11(NS2-80))
Contact Configuration: 1 Normally Open + 1 Normally Closed
Rated Insulation Voltage (Ui): 690V
Conventional Thermal Current (Ith): 6A
Rated Impulse Withstand Voltage (Uimp): 4kV (Value from standard NS2-AU, verify if NS2-80 specific differs, though likely the same)
Rated Operational Current (Ie) & Voltage (Ue):
AC-15:
3.3A @ 230/240V
2.2A @ 380/415V
(Other AC-15 ratings likely same as standard NS2-AU11: 1.5A@440V, 1A@500V, 0.6A@690V)
DC-13:
0.5A @ 220V
(Other DC-13 ratings likely same as standard NS2-AU11: 1.3A@110V, 3A@60V, 5A@48V, 6A@24V)
Terminal Markings (Typical): (73)43-44(74) for NO, (61)31-32(62) for NC
Standards: Conforms to auxiliary contact requirements within IEC/EN 60947 standards.
Applications utilizing NS2-80 motor starters that require external status signaling.
Industrial control panels needing interlocking logic involving high-current motors controlled by NS2-80 starters.
Adding run/stop indication lights to NS2-80 starter installations.
Connecting NS2-80 starters to PLC systems or other automation controllers.
Installation: Always de-energize the NS2-80 starter before attaching the auxiliary contact. Align the block with the mounting provision on the left side of the starter and firmly push until it securely latches (See Figure 5 in NS2-80 User Instruction).
Wiring: Connect control circuit wiring to the appropriate terminals (e.g., 43-44 for Normally Open, 31-32 for Normally Closed). Use correctly sized wires and ensure secure terminal connections.
Compatibility: This unit (AUX-NS2-80-AU11 / NS2-AU11(NS2-80)) is specifically intended for the NS2-80 series starters.
Testing: After installation, cycle the NS2-80 starter handle (if safe) and verify the state change of both the NO and NC auxiliary contacts using a multimeter or continuity tester.
