Phoenix Contact DEK-OE- 12DC/48DC/100 Series Solid State Relay

These DIN rail mount opto-couplers 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 optocoupler from Phoenix Contact transmits an electrical signal between two isolated circuits. For ease of use, an LED (light-emitting diode) gives off an infrared light that activates a photosensitive device to illuminate a yellow LED, providing a clear visual indicator of the optocoupler's status.
Its compact card construction fits easily into modular terminal blocks, even when space in your set-up is limited. It has M3 screw threads, so you can screw it securely in place for a reliable connection. The output circuit is protected against reverse polarity to prevent electric shock hazards, and the circuit also contains a damper diode to reduce spikes in voltage that could cause short circuits.
You can use this optocoupler to prevent electrical interference in your programmable logic controller (PLC). A fast response time of 20μs (microseconds) means it provides quick and efficient results.
