The recommended PCB layout and land pattern can be found in the Standex-Meder Electronics' application note or by contacting their technical support team. It's essential to follow the recommended layout to ensure proper relay operation and to prevent overheating or electrical noise issues.
To ensure proper relay operation, the drive circuit should be designed to provide a clean, rectangular pulse with a sufficient voltage and current to fully energize the relay coil. The recommended drive voltage and current can be found in the datasheet. Additionally, the relay should be switched at a frequency that allows for proper settling time to prevent contact bounce or oscillation.
The maximum switching frequency of the DIL-CL-1A81-4/4-18M is typically limited by the relay's mechanical characteristics and the application's specific requirements. As a general guideline, the relay can be switched at frequencies up to 100 Hz, but this may vary depending on the specific use case. It's recommended to consult with Standex-Meder Electronics' technical support team for more information.
To minimize EMI and RFI issues, it's essential to follow proper PCB design and layout practices, such as using a solid ground plane, keeping signal traces short, and using shielding or filtering components as needed. Additionally, the relay's coil and contacts should be properly bypassed and filtered to prevent electromagnetic radiation.
The operating temperature range of the DIL-CL-1A81-4/4-18M is typically -40°C to +125°C, but this may vary depending on the specific application and environmental conditions. It's essential to consult the datasheet and application notes for more information on temperature derating and reliability.
