ANALOG INPUTS
Pt100/Pt1000 connection
The connection for the channels is made to the terminals in accordance with the figure at
the left. The 3-wire connection from the Pt100 sensing element to the FieldLogger input
guarantees the cancellation of the error caused by the resistance of the wires. All three
wires must have the same gauge and length.
For the two-wire Pt100, interconnect terminals 1 and 2.
Thermocouple connection
The connection for the channels is made in the terminals in accordance with the figure at
the left. Please observe the correct connection polarity.
Cables used for connecting thermocouples must have the same thermoelectric
characteristics of the used thermocouple (compensation cable or extension cable), and
also must be connected with the correct polarity.
The non-use of compensation cables or the use with the incorrect polarity can cause
significant measurement errors.
Voltage (mV) connection
The connection for the channels is made in the terminals in accordance with the figure at
the left. Please observe the correct polarity of the connection.
Voltage (V) connection
The connection for the channels is made in the terminals in accordance with the figure at
the left. Please observe the correct polarity of the connection.
Current (mA) connection
The connection for the channels is made in the terminals in accordance with the figure at
the left. Please observe the correct polarity of the connection.
