Connection to Relay Output

Helios IP Audio Kit is equipped with one galvanically isolated relay switch with

N/O and N/C contacts on the NC, NO and COM terminals. The relay function is
programmable.

Connection to Digital Outputs

Helios IP Audio Kit is equipped with two active 12 V / 650 mA outputs on the

OUT1 and OUT2 terminals. The outputs are overload and short-circuit resistant. The

output function is programmable.

Connection to Digital Inputs

Helios IP Audio Kit is equipped with two digital inputs on the IN1 and IN2 te

rminals. The digital inputs recognise the following two logic levels: log. 0 for voltage
under 1.1 V a log. 1 for voltage over 3 V. Keep the voltage polarity to make the

function work properly. The function is programmable for either input.

Warning

Do not exceed the voltage and current limits for the load connected to the
relay contacts as specified in the technical parameters of the device to
avoid device damage.
