SPIDER44/03 / SPIDER04/03_EN_2018/07_REV_2020/02
The device has 8 digital inputs, which are primarily designed for the detection of low-level operating and fault
conditions. This includes the monitoring of fault signals of ampli
fi
ers, monitoring of cabinet temperature by
thermostats, etc. A remote control, that is, an output follows at any point of the system the input is also pos-
sible. Each input state can be inverted for further processing by the software.

The device has 8 digital open collector transistor outputs. They are used for switching relays, lamps of lo-
wer power, etc. Typical applications are the display of faults, switching off other audio devices during an
announcement and more.
