DIGITAL INPUTs

The product has 2 digital inputs. These inputs are used to signal an event in
the product (See WaveOS user manual). The signal must be applied on the
pins IN1 or IN2 of the digital I/O connector.
The voltage applied must not exceed 24 VDC. The product interprets any
voltage between 0V and 2V as a logic level "0", and any voltage between 3V
and 24V as a logic level "1". Between 2V and 3V, the state is undetermined.
DIGITAL OUTPUTs (ALARM CONTACTOR)
The product has two digital outputs in order to signal an alarm defined by the
configuration of the product (See WaveOS user manual). The alarm uses the
pins OUT1 or OUT2 of the digital I/O connector.
The contact is closed during normal product operation and opens when the
alarm condition occurs. It opens as well when the product is powered off or
not in an operational state.
The alarm contact can switch 60V maximum voltage with a current up to
80mA, and protected against transient surges. This is a first stage alarm
contactor which must not be used to drive power directly. To carry out this
function, please consider the use of a power relay, as shown in the picture
below:
