G9SA-501

The Omron G9SA-501 is a Safety Relay Unit designed to ensure secure and reliable operations in safety-critical applications. It is compatible with two different power supply voltages, supporting 24 VAC/VDC with a frequency of 50/60 Hz or 24 VDC, and 100 to 240 VAC with a frequency of 50/60 Hz. The operating voltage range is set between 85% to 110% of the rated power supply voltage to ensure stability and safety. With a low contact resistance of 100 mΩ, the relay unit ensures minimal power loss and efficient performance. Its fast operating time of 30 ms and response time of 10 ms enable a quick and accurate response to safety conditions. The unit provides an isolation voltage (Ui) of 250 VAC and an impulse withstand voltage (Uimp) of 4 kV, offering reliable protection against voltage spikes. The G9SA-501 exhibits excellent electrical characteristics with an insulation resistance of 100 MΩ (at 500 VDC) between input and output, ensuring safe and stable operations. It is also designed to withstand vibration with a frequency range of 10 to 55 Hz and shock with a resistance of 300 m/s2 for destruction and 100 m/s2 for malfunction. With a mechanical durability of 5,000,000 operations and electrical durability of 100,000 operations, the G9SA-501 is built for long-lasting performance in demanding environments. Its low failure rate and wide operating temperature range of -25 to 55°C further enhance its reliability. The unit is designed to withstand tough conditions while maintaining consistent and secure operations. With a terminal tightening torque of 0.6 N·m, the Omron G9SA-501 ensures secure connections and is an excellent choice for ensuring safety in critical applications.
