nc1-f5-d2 chint pneumatic timer, 0.1-30s ‘off’ delay contactors

Why Choose the CHINT NC1-F5-D2 Pneumatic OFF-Delay Timer?

The CHINT NC1-F5-D2 is a reliable pneumatic OFF-delay timer module designed to add time delay control functionality to CHINT NC1 series contactors in industrial automation and motor control applications. As part of the CHINT NC1 contactor accessory range, it provides controlled delayed switching after contactor de-energisation, helping improve sequence control and system performance.

This timer accessory mounts directly onto compatible CHINT NC1 contactors and uses a pneumatic timing mechanism to provide dependable operation without requiring a separate control power supply. Its compact design makes it suitable for electrical control panels, OEM machinery and industrial automation systems where controlled shutdown timing is required.

With an adjustable delay range of 0.1–30 s and timed auxiliary contacts, the NC1-F5-D2 is ideal for applications requiring delayed switching functions such as motor stopping sequences, ventilation systems and automated production equipment.

Reliable Timing Control for Industrial Automation

Pneumatic timer modules allow electrical systems to introduce controlled switching delays into contactor circuits. The NC1-F5-D2 provides an OFF-delay function, meaning the timing sequence begins when the contactor coil is de-energised, allowing connected equipment to continue operating for a defined period before switching off.

The CHINT NC1-F5-D2 supports machine builders and automation engineers by providing simple and reliable timing control without requiring complex electronic timing equipment. It is commonly integrated into motor control systems, production machinery and industrial control panels.

Typical Applications

• Industrial motor control panels.
• Motor stopping and delayed shutdown circuits.
• Conveyor and material handling systems.
• Ventilation and fan control equipment.
• Production and processing machinery.
• OEM automation control systems.
