Preset Configurations
Is there a Preset Configuration available that solves this application? Look in the
Preset Configuration booklet.
We can adapt the default configuration for this application.
Selection of I/O
We need two analogue inputs, one digital input, one digital output and one analog
output.
The temperature transmitter TT1 has a 0–5 V output; the flow transmitter FT1 has
a 0–20 mA output.
The inputs and outputs should be connected as shown in the figure below.
The temperature transmitter TT1 is connected to AI1 and has its own independent
power supply.
The flow transmitter FT1 connected to AI2 is to take its power supply from the
controller. To configure AI2 as a single ended current input, jumpers 3 and 4 must
be closed.
