AirGate-GPRS
NOVUS AUTOMATION 11/29
INPUTS
There are two input channels that can be individually configured using internal jumpers such as input 4-20 mA, input 0-10 V
or digital input. There is no insulation between channels.
The jumper access requires the opening of the AirGate-GPRS. Their location can be seen in the following illustration:
*
The AirGate-GPRS is factory configured as a digital input in both channels.
Digital Signal Wiring
When configured as a digital input, it can be connected to a voltage output (check the acceptable levels in the
Specifications section), a dry-contact output or a NPN output. Be careful when connecting multiple outputs due to the
lack of insulation between the AirGate-GPRS inputs.

Connection Current (mA)
Channels connection in the terminals should be done as shown in the figure on the left.
Check the correct connection polarity.
