Outputs
Three general purpose outputs are available.
Pin Name Function
8 OUT 1+ Configurable digital output 1 – positive pin
22 OUT 1- Configurable digital output 1 – negative pin
11 OUT 2+ Configurable digital output 2 – positive pin
12 OUT 2- Configurable digital output 2 – negative pin
16 OUT 3A Configurable digital output 3 – polarity insensitive
17 OUT 3B Configurable digital output 3 – polarity insensitive
The function of the three outputs OUT1, OUT2 and OUT3 can be defined by the user. Refer to
Genius™ Help On-Line for further details.
By default, OUT1 is associated with the COMPLETE READ event, which activates when the
code has been read correctly. In case the reader has been programmed to read several codes
within the same reading phase, the event activates when all codes have been read.
OUT2 is associated with the NO READ event, which activates when no code has been read.
OUT3 is associated with NONE, which means that the output is always in the Line State.
The OUT1 and OUT2 electrical features are given below:
Collector-emitter voltage 30 V Max.
Collector current (pulse) 130 mA Max.
Collector current (continuous) 40 mA Max.
Saturation voltage (VCE) 1 V at 10 mA Max.
Maximum power dissipation 90 mW at 50°C (Ambient temperature).
The limit requested by the maximum power dissipation is more important than that of the
maximum collector current: if one of these outputs is continuously driven, the maximum
current must not be more than 40 mA although 130 mA may be reached in pulse conditions.

When the load is powered by an external power supply, the voltage must not exceed 30 V.
OUT3 has different electrical features, since it is a bi-directional solid state relay with built-in
current limit protection. If this output is continuously driven, the maximum current must not be
more than 200 mA although more than 300 mA may be reached in pulse conditions for an
ambient temperature of 25°C. At the maximum ambient temperature of 50°C the maximum
respective current is 150 mA continuous and 240 mA pulse.
