Designed for time-critical safety scenarios, the Omron G9SE-221-T30 features an extended OFF-delay time of 30 seconds, allowing machinery to power down gradually after a safety input is triggered. This makes it ideal for applications such as conveyor systems, robotic arms, and motors where an immediate stop may lead to operational damage or safety risks. Powered by a stable 24 VDC rated voltage, it operates efficiently within a voltage range of β15% to +10%, providing tolerance for minor power fluctuations common in industrial facilities.
The G9SE-221-T30 ensures dependable response with a 15 ms response time and a maximum operating time of 100 ms. With a power consumption of just 3 W, it supports energy-efficient panel design without compromising on performance. Its rugged construction offers shock resistance up to 300 m/sΒ² and vibration resistance from 10 to 55 Hz at 0.7 mm double amplitude, making it suitable for high-vibration environments like machine shops, assembly lines, and heavy industry. It performs reliably across a wide ambient temperature range from β10Β°C to 55Β°C and in humidity levels up to 85% RH, ensuring durability in Indian climates.
At just 180 g, this compact, DIN-rail mountable safety relay unit is easy to install and integrates smoothly into existing safety circuits. Trusted by automation engineers and OEMs, the Omron G9SE-221-T30 offers a reliable solution for extended delay-based safety control.
