4.3.2. Optocoupler input
Digital signals, e.g., for feedback from a connected door, can be received via the optocoupler input.
The Opto input is a potential-free input, i.e., a voltage and ground (GND) must be applied.
The voltage or GND can be used from the VOut connection terminals as shown in the connection example (see Figure 6, “Connection to a turnstile”.
Observe the maximum permissible input voltages and currents (see Technical data). Connected components must comply with the relevant safety standards (IEC 60950-1 or IEC 62368-1).
