Digital output (IO-2)

The device has four isolated digital outputs with a shared common pin. The digital
outputs are polarity free. The digital output can be used for controlling low current
external devices. The output is a CMOS relay which is protected by a PTC type
fuse. The output is capable of handling a continuous current of 100 mA maximum
at an ambient temperature of 20°C.

DC output

The input voltage to the power supply connector is circulated back to the I/O
connector of the device. This DC output can be used, for example, together with
digital outputs in order to simplify external circuitry and wiring.
