For flexibility, the four safety contacts include two instantaneous enabling circuits and two time-delayed enabling circuits. This means you can precisely tailor your safety solutions for situations where a few seconds can make a big difference. Use this versatile device with both electromechanical switches and contact-free protection equipment such as light barriers and laser scanners.
