Inputs are not voltage polarity conscious when in driven mode
and can be wired either way around.

Volt-free mode supplies a low current from a local 5V supply to
sense the contact position. This is common to all inputs and care must
be taken to avoid swapping the common on non-isolated systems.
Warning:
Do not exceed 30 V ac or 60 V dc input
potential, risk of shock.
The maximum input voltage when Driven mode is
selected is 12 V dc or ac. This is due to the current
limiting resistor in each input circuit reaching its
maximum power threshold. If higher voltages are a
system requirement then a relay should be used to
isolate the inputs from the source.
Warning:
Do not exceed 12 V dc/ac input drive
or damage might occur to unit.
4.5.2 Connecting to sources greater than 12 V
A relay should be used to isolate the input from any
sources that are greater than 12 V.

The Sonix Io input should be configured as volt-free when using
an external isolating relay.
4.5.3 Polarity
Polarity of the inputs are configured by SAS and can be
either normally open or normally closed. The unit will
ignore its inputs until after the configuration has been
loaded on a cold start to avoid incorrect latch up. This
takes approximately 7 seconds.
4.6 Output connections
The Sonix Io output ports are volt-free relay contacts
with hardware selectable normally open or normally
closed. The relays controlling the outputs are small low
power variants and are only rated for 1A at 24 V dc.
Warning:
Do not exceed 30 V ac or 24 V dc on
the relay contacts.
4.6.1 Extended voltage or duplicate output support
For controlling voltages in excess of 24 V dc / 30 V
ac a correctly rated external relay should be used to
provide the isolation. Also, if multiple independent
outputs are required by the system design, then
isolation should be maintained by using an external
relay with multiple contacts.

4.6.2 Polarity
The polarity of the outputs is set by a 2-position
jumper link for each output. These can be found
adjacent to each output on the PCB.
