CHINT Front Mount Auxiliary Contact 1NO+1NC

• The CHINT AUX-NS2-AE11 is a front-mounting auxiliary contact block designed for use across the NS2 series manual motor starters (including NS2-25, NS2-32, NS2-80, and NS2-80B variants).
• This compact accessory easily attaches to the front face of the starter, providing one Normally Open (1NO) and one Normally Closed (1NC) contact.
• These contacts operate synchronously with the starter's main contacts, offering a convenient way to integrate the starter's status into control circuits for signaling or interlocking purposes, especially where side mounting space is limited.

Features

• Contact Configuration: 1NO + 1NC

• Mounting Type: Front Mount / Front Hanging

• Compatibility: Broadly compatible with NS2 series starters (NS2-25, NS2-32, NS2-80, NS2-80B families)

• Easy Snap-On Installation to the starter's front face

• Provides Electrically Isolated Contacts for control voltage circuits

Benefits

• Space-Saving Design: Mounts on the front, ideal for installations with limited side clearance.

• Remote Status Indication: Enables external monitoring of the starter's ON/OFF state via indicator lights or PLC inputs.

• Control Circuit Interlocking: Allows for creating safety or sequential logic based on the starter's position.

• Simple Integration: Easily adds signaling capability to manual starters for basic automation or monitoring.

• Versatile Contacts: Provides both NO and NC states to suit different control circuit requirements.

Ideal Use

• Adding starter status feedback in control panels where side space is restricted.

• Basic interlocking schemes involving NS2 starters.

• Driving low-power indicator lamps or relay coils based on starter status.

• Connecting NS2 starter status to PLC digital inputs.

Tips

• Installation: Ensure the motor starter is de-energized. Align the AE11 block with the front mounting features/slots on the NS2 starter and press firmly until it securely clips into place. Refer to relevant assembly diagrams (e.g., Fig 4 for NS2-80, Fig 9 for NS2-25/32/32H). For some models, a screwdriver might be needed to manipulate a central slot during fitting.

• Wiring: Connect control wires to the designated terminals (13-14 for NO, 21-22 for NC). Use appropriate wire gauge for control circuits and ensure terminals are tightened properly.

• Testing: After installation, manually operate the starter (if safe) and verify the auxiliary contacts change state correctly using a continuity tester or multimeter. Check reliable mechanical coupling between the starter and accessory mechanism.
