Crouzet 81523601 Pneumatic Memory Module with Manual Override

The Crouzet 81523601 is a compact pneumatic memory module designed for industrial automation and control systems. This bistable relay element maintains its state (set or reset) until an opposing signal is received, making it ideal for sequential logic operations in pneumatic circuits. It features a manual override for easy testing and maintenance, enhancing reliability in applications such as assembly lines, packaging machinery, and process control. Key benefits include high durability in harsh environments, quick response times, and compatibility with standard pneumatic tubing. Compared to electronic alternatives, it offers immunity to electromagnetic interference and operates without electricity, reducing energy costs and simplifying installation in explosive atmospheres. Drawbacks may include limited scalability for complex logic compared to PLCs and the need for compressed air supply. With push-in connections for 4mm tubes, it supports operating pressures from 2 to 8 bar and temperatures from -5°C to 50°C. This module is new, as indicated by packaging and condition, and is suitable for DIN rail mounting. Overall, it provides a cost-effective, robust solution for pneumatic logic, backed by Crouzet's reputation for quality automation components.
