1.5 Rear Terminal Layout and Wiring
Wiring graph for instruments except D and D2 dimension.
Note 1: For linear voltage input, if the range is
below 500mV, connect to terminals 19 and 18.
0
～
5V or 1
～
5V signal can be inputted from
terminals 17 and 18.
Note 2: 4
～
20mA linear current signal can
change to 1
～
5V voltage signal by connecting
a 250 ohm resistor, and then be inputted from
terminals 17 and 18. If I4 module is installed
in MIO slot, 4
～
20mA signal can be inputted
from terminals 14+ and 15-, and 2-wire
transmitter can be inputted from terminals 16+
and 14-.
Note 3: The compensation wires for different
kinds of thermocouple are different, and
The graph suits for upright instruments
with dimension A or E
For instruments with dimension F,
just clockwise rotate the graph 90
degree, and the numbers of the
terminals keep the same.
