567 Series Optocouplers

The 567 Series Optocouplers are high-isolation, solid-state devices designed for galvanic separation in intrinsically safe circuits. Certified to ATEX and IECEx standards, they are ideal for use in hazardous environments such as flammable gas zones, mining operations, and medical facilities where electrical safety and reliability are critical.

With a minimum isolation voltage of 4,000 VDC, insulation resistance up to 10¹³ Ω, and fast switching times of 0.5 µs, the 567 Series supports both analog and digital signal transmission. These optocouplers feature a photo-diode output for short cycle times and offer signal inversion capability, making them suitable for complex control logic.

Their compact design includes 14 mm creepage and air path distances, ensuring compliance with stringent safety standards. The non-mechanical switching mechanism provides long operational life and immunity to magnetic fields, making them a robust solution for demanding industrial applications.

Type of protection: II (1) G [Ex ia Ga] II C
In accordance with: EN 60079-0, EN 60079-11
