3.10 Inputs

3.10.1 Optocoupler

The optocoupler inputs in Terminal X5 are galvanically isolated from the Reader electronics and
must therefore be externally supplied. The input LEDs for the optocouplers are switch internally
with a series resistor of 500 Ω. For supply voltages of greater than 10V the input current must be
limited to max. 20 mA by an additional external series resistor (see

Table 3-7: Optocoupler input pin assignments
Notes:
•
The inputs are configured for a maximum input current of 24 V DC and an input current
of maximum 20 mA.
•
Reversing the polarity or overloading the inputs will destroy them.
•
The Reader supply voltage must not be used to drive the inputs, since otherwise
additionally induced noise may reduce the effective reading range.
