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

Isolate equipment on your electrical circuit using this optocoupler terminal block from Phoenix Contact. This safety device can isolate voltages between input and output at 2.5kVrms (kilovolts root mean square) for a high level of protection. As a solid-state relay, it uses electrical signals for switching without mechanical parts, reducing the risk of wear. It has a fast response time of 40μs (microseconds), so it will react quickly to protect your equipment.
Thanks to its compact dimensions of 80 (length) x 6.2 (width) x 56mm (depth), it takes up a minimal amount of space on your panel. Clear labelling above each contact and DIN rail clips make it simple to install. A yellow LED (light-emitting diode) gives you a clear status indication for ease of use. Phoenix Contact's signature green casing helps you quickly identify it in a complex set-up for ease of maintenance and organisation.

• Can be mounted in any position for maximum flexibility
• Wide operating temperature range of -20°C to +60°C for use in demanding environments
• Isolation voltage of 2500V for use in high-power industrial circuits
