Optocoupler output (X6/1-2):
The transistor connections, collector and emitter, of the optocoupler output are galvanically isolated
from the Reader electronics and are carried to the outside without any internal ancillary circuitry on
Terminal X6. The output must therefore be powered by an external power supply.
Note:
• The output is configured for max. 24 V DC / 30 mA.
•
Polarity reversal or overload on the output will destroy it.
•
The output is intended for switching resistive loads only.
Optocoupler input (X6/3-4):
The input LED associated with the optocoupler is connected internally to a series resistor of 500 Ω.
For supply voltages of greater than 10V the input current must be limited to max. 20 mA by means
of an additional series resistor (see Table 2-7).
Table 2-7 shows the necessary external resistors for various external voltages U
Notes:
•
The input is configured for a maximum input voltage of 24 V DC and an input current of
max. 20 mA.
•
Polarity reversal or overload on the input will destroy it.
