CHINT Side Mount Auxiliary Contact 1NO+1NC (NS2-80)

• The CHINT AUX-NS2-80-AU11 is a side-mounting auxiliary contact block specifically designed for compatibility with the larger frame NS2-80 series rotary manual motor starters.
• This unit provides one Normally Open (1NO) and one Normally Closed (1NC) auxiliary contact set that operates synchronously with the main starter mechanism.
• It enables the integration of the NS2-80 starter's operational status into external control circuits, crucial for remote monitoring, system interlocking, and advanced automation tasks.

Features

• 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

Benefits

• 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.

• Standards: Conforms to auxiliary contact requirements within IEC/EN 60947 standards.

Ideal Use

• 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.

Tips

• 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.
