Dry Contact Connection
The connection to the Digital Input with a Dry Contact-type sensor is made at the terminals
according to the following image.

ANALOG INPUTS
Pt100 Connection
The connection to the channels is made at the terminals according to the following image. The
three-wire connection from the Pt100 sensor element to the
LogBox Wi-Fi
input guarantees
the error cancellation caused by the wires resistance. The three wires should have the same
gauge and length.
For two wire PT100, connect the RTD to terminals 6+7 and link 7 to 8.
Thermocouples Connection
The connection to the channels is made at the terminals according to the following image. You
must observe a correct connection polarity.
Cables used for thermocouples connection must have the same thermoelectric characteristics
of the thermocouple used (compensation cable or extension cable) and must be connected with
the correct polarity.
Failure to use compensation cables or their use with incorrect polarity can lead to large
measurement errors.
Voltage Connection (mV)
The connection to the channels is made at the terminals according to the following image. You
must observe a correct connection polarity.
Current Connection (mA)
The connection to the channels is made at the terminals according to the following image. You
must observe a correct connection polarity.
Voltage Connection (V)
The connection to the channels is made at the terminals according to the following image. You
must observe a correct connection polarity.
