nc1-f5-d4 chint pneumatic timer, 10-180s 'off' delay contactors

Why Choose the CHINT NC1-F5-D4 Pneumatic Timer?

The CHINT NC1-F5-D4 is a reliable pneumatic OFF-delay timer module designed for use with the CHINT NC1 contactor series. Engineered for industrial automation and motor control systems, this accessory provides accurate delayed switching functionality for electrical control circuits requiring controlled disconnection timing.

Featuring an adjustable 10 to 180 second OFF-delay timing range, the NC1-F5-D4 enables controlled circuit interruption after the contactor coil is de-energised. This makes it ideal for sequencing operations, motor stopping delays, ventilation systems, machinery control and industrial automation applications requiring extended timed OFF-delay functionality.

The module mounts directly onto compatible CHINT NC1 contactors and includes 1 normally open and 1 normally closed timed auxiliary contact. Its pneumatic timing mechanism provides dependable operation without requiring a separate control power supply, making it suitable for demanding industrial environments and OEM machine building applications.

Reliable Timing Control for Industrial Automation

Pneumatic timers are widely used in industrial automation systems to introduce controlled switching delays into electrical control circuits. The NC1-F5-D4 provides an OFF-delay function, meaning the timing sequence begins when the contactor coil is de-energised, allowing connected equipment to continue operating briefly before switching off.

This type of timer is commonly used in ventilation systems, motor stopping circuits, conveyor systems and machine sequencing applications where controlled shutdown timing improves operational reliability and process control. The pneumatic timing mechanism offers dependable operation with minimal maintenance requirements.

Typical Applications

• Industrial automation systems.
• Motor control and stopping circuits.
• HVAC and ventilation systems.
• Conveyor and process control systems.
• Machine sequencing operations.
• OEM electrical control panels.
