1.5 Rear Terminal Layout and Wiring
Wiring graph of instruments
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 should be directly
connect to the terminals. When the internal auto
compensation mode is used, connecting the common
wire between the compensation wire and the terminals
will cause measurement error.
Note 4: When main output selected linear current or SSR voltage, output form terminal 13+, 11-,
The graph suits for upright instruments
with dimension A or E
For instruments with dimension F or B,
just clockwise rotate the graph 90
degree, and the numbers of the
terminals keep the same.
