Dry Contact Connection
The conn
ection to the digital input using a Dry Contact-type sensor is made at the terminals
according
to the following image.
ANALOG INPUTS
Pt100 Connection
The conn
ection 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 BLE
input guarantees the
error canc
ellation caused by the wires resistance. The three wires should have the same gauge
and length.
For two wires PT100, connect the RTD to terminals 6+7 and link 7 to 8.
Ther
mocouples Connection
The conn
ection to the channels is made at the terminals according to the following image.
Observe correct connection polarity.
Cables us
ed for thermocouples connection must have the same thermoelectric characteristics
of the th
ermocouple used (compensation cable or extension cable), and also must be
connected with the correct polarity.
Failure to use compensation cables or their use with incorrect polarity can lead t
o large
measurem
ent errors.
Voltage Connection (mV)
The connection to the channels is made at the terminals according to the following
image.
Observe c
orrect connection polarity.
Current Connection (mA)
The conn
ection to the channels is made at the terminals according to the following image.
Observe c
orrect connection polarity.
Voltage Connection (V)
The connection to the channels is made at the terminals according to the following
image.
Observe correct connection polarity.
