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

This solid state optocoupler from Phoenix Contact lets you safely switch electrical equipment on and off. It isolates input and output circuits to limit interference while transmitting current between them. A quick response time of 40μs (microsecond) in the input circuits makes this device reliable in demanding industrial applications, while the LED display means you can easily monitor its operating voltage.
The output circuits have a large voltage range between 3 and 30V DC, so this optocoupler is suitable for a wide range of systems. For added safety, it comes with reverse polarity and surge protection, which cuts off power if it's plugged incorrectly or if an electrical malfunction occurs. The signature Phoenix Contact green housing makes the unit easy to identify during routine maintenance, and its compact dimensions of 80 (height) x 6.2mm (width) mean it fits easily into tight spaces.

• Low weight of 21.33g for minimal strain on equipment
• Broad operating temperature range of -20°C to +60°C for use in extreme environments
• Can be mounted in any position for design flexibility
