With the 4-way optocouplers you ensure reliable signal separation between the signal generator and the electronic control
The integrated 4-way optocoupler protects your control logic through galvanically separated signal transmission (switch open or closed) between the electronic control and the system to be controlled. The circuits carried out by your control system (closed and opened) are output to the transistor switches at the output via four optocouplers.
The already integrated power supply is used for the galvanically isolated power supply of your electronic control system (e.g. PLC) with 24VDC. In the case of the Opto2-01 optocouplers, the fourth optocoupler is also designed as a switchable voltage source with an electrically isolated input.
Since the power supply unit is already integrated in these 4-way optocouplers, the space requirement and the wiring effort are much lower than with 4 individual optocouplers with separate power supply units. In addition, wiring errors are avoided. The 4-way optocouplers are suitable for direct mounting on a 35mm top hat rail or with screws on the wall.
