Crouzet Pneumatic Timer Adjustable Negative Time Delay Module 2-8 Bar Operating Pressure 0.1-15 Seconds 81 Series 81506710

The Crouzet 81506710 Pneumatic Timer is an adjustable negative time delay module that operates efficiently within a pressure range of 2 bar to 8 bar. It features a timing range from 0.1 seconds to 15 seconds, making it highly versatile for industrial pneumatic timing applications.

Upon application of a pilot signal, the timer's reservoir begins to fill through the integrated flow restrictor. After the set time delay, the relay is activated, providing an output signal. Importantly, the timer maintains its state and will not reset until the pilot signal is removed, ensuring reliable timing control.

This timer is designed for installation on DIN rails, facilitating straightforward mounting in control panels. It can operate reliably in temperature conditions ranging from -5°C to 50°C, suitable for diverse industrial environments.

The device features an orifice diameter of 2.7 mm and supports a flow rate of 170 NL/min at 6 bar operating pressure. Its mechanical lifespan is robust, exceeding 10 million cycles, underscoring its durability in demanding applications.

Crouzet’s pneumatic timer complies with several key industrial standards and certifications, including ATEX for hazardous area certification, 94/9/ECC, ANSI/ESD S20.20:2014, and BS EN 61340-5-1:2007, ensuring safety and reliability.

The timer operates by filling a reservoir via a flow restrictor upon pilot signal application. Relay activation occurs after the preset time delay and does not reset until the pilot signal is removed. Includes DIN rail mounting for easy integration into control panels.

Functional temperature range from -5°C to 50°C allows for versatile application environments. Orifice diameter of 2.7 mm and flow rate of 170 NL/min at 6 bar ensure precise pneumatic control. Mechanical operating life exceeds 10 million cycles, ensuring long-term reliability.

Certified to ATEX, ANSI/ESD S20.20:2014, and BS EN 61340-5-1:2007 standards.
