3.3 Power supply
DINplayer may operate with the following voltage power supplies: 12÷24VDC.
In the case of configuration with power amplifier, the use of a suitable power supply is
recommended to supply the required audio power . With a 4
Ω
loudspeaker, DINplayer can
absorb current peaks of 2A.
The standby consumption is 1W.
3.4 Vplay output for external relay
The output of the DINplayer is of a transistor type and is
optoisolated towards the inside CPU.
When activated, it provides on the output terminal the
same feeding voltage applied on the module. This voltage
may be applied to the input of a PLC or else it may
directly pilot the spool of an outside relay.
The output can provide a maximum current of 150mA and
is equipped with a protection diode for inverse currents
induced by the spool of any outside relay.
The output is activated at the time when the reproduction
of an audio file starts, and is maintained in this state
throughout the duration of the file.
