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

Ensure quick switching between the 'on' and 'off' states of your electrical device using this optocoupler from Phoenix Contact. It keeps the input and output circuits isolated while acting as a safe link to transmit current without interference. The circuits remain apart even under extreme voltages as high as 2500V, so the unit is suitable for high-powered applications.
For additional safety and to limit potential damage, the input circuits have a reverse polarity diode which cuts off power if they're connected incorrectly. You'll find it easy to monitor the optocoupler's performance, thanks to the yellow LED (light-emitting diode) signal. With a large output voltage range between 4 and 30V DC and a wide operating temperature range between -20°C and +60°C, you can use it reliably in demanding industrial situations. Standard DIN rail mounting lets you install it quickly on a panel without complex tools.

• Light weight of 21.46g so adds minimal strain on your panel
• Suppressor diode protects output circuits from electrical surges
