Digital inputs: 0 - 3, 4 - 9
Voltage level: low = min. 0V - max. 1.8V; high = min. 3V - max. 24V DC (+ 20%)
Input currents: dependent on input voltage; input resistance = 46 kOhm
Digital outputs: 0 - 3
Switching capacity when supplied by the Fronius Datamanager 2.0 plug-in card:
3.2 W in total for all 4 digital outputs
Switching capacity when supplied by an external power supply with min. 12.8 - max.
24 V DC (+ 20%), connected to Uint/Uext and GND: 1 A, 12.8 - 24 V DC (depend-

The connection to the I/Os is made via the supplied mating connector.
Antenna plug
For screwing on the WLAN antenna
Modbus termination switch (for Modbus RTU)
Internal bus termination with 120-ohm resistance (yes/no)
Switch in "on" position: Termination resistance of 120 Ohm active
Switch in "off" position: No termination resistance active
IMPORTANT! The termination resistance must be active for the first and last device
in an RS-485 bus.
For switching between master and slave mode within a Fronius Solar Net ring
IMPORTANT! All LEDs on the Fronius Datamanager 2.0 plug-in card are off in
slave mode.
