By default, OUT1 is associated with 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 NO READ event, which activates when no code has been read.
OUT3 is associated with NONE, which means that the output is always in 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 be less than 30 V.
OUT3 has different electrical features, since it is a bi-directional solid state relay with a
built-in current limit protection. If this output is continuously driven, the maximum current
must be not 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.
The OUT3 electrical features are given below:
Maximum voltage ± 100 V
Collector current (pulse) 240 mA Max.
Collector current (continuous) 150 mA Max.
R on 6 – 15 Ω
R off > 500 Ω
Off-state leakage current < 1 µA
Maximum power dissipation 550 mW at 50°C (Ambient temperature).
