These DIN rail mount opto-couplers from Phoenix Contact provide an ideal means of interfacing on/off signals to, or from, equipment, whilst providing electrical isolation between their own inputs and outputs. In other words, these may be used to protect equipment by electrically isolating its inputs, outputs, or both. The dc/ac and ac/dc versions also provide a means of interfacing (whilst isolating) ac and dc control voltages.

• Dc in/Dc out, Dc in/Ac out and Ac in/Dc out versions available
• Versions with switching speeds up to 100kHz available
• 2.5kVac input to output isolation
• LED status indication
• Module width 6.2mm
• Operating temperature range: -20 to +60°C

IEC 60 664, IEC 60 664A, DIN VDE 0110

Protect your equipment from electrical damage with this optocoupler from Phoenix Contact. The integrated protection of outputs and inputs prevents damage from reverse polarity and current surges. It's a solid-state relay that uses electrical rather than mechanical switching to reduce wear. It also offers a quick response time of 250μs (microseconds) for maximum efficiency and fast protection.
This user-friendly terminal block module features an LED (light-emitting diode) status indicator for ease of use as well as clear labelling to help you with set-up. It's designed for mounting on universal DIN rails and features simple clips for a secure connection and versatile mounting in any position. The compact dimensions of 80 (height) x 6.2 (width) x 56mm (depth) mean that it will take up minimal space on your distribution panels.

• Screw connection for a secure attachment that won't come loose
• Suitable for cables ranging in size between 24 and 12AWG (American Wire Gauge) for use in a variety of applications
• Broad operating temperature range of -20°C to +60°C for use in harsh environments
• High isolation voltage of 2500V for use in heavy-duty industrial applications
