Analogue outputs and temperature control

Analogue outputs control

Figure 1 : Special control cable for analogue outputs
An external socket from the transmitter (for certain
versions) fixed on the lower part of the front panel
allows to measure the value of the analogue output
current by inserting a miliampere- meter in the current
loop
A special cable
provided as an option , gives access, when connected,
to the following signals :
I1+: brown flex
I1- : yellow flex
I2+ : white flex
I2- : green flex
Reading in mA between the yellow and brown wires
gives the current value of output 1.
Reading in mA between the white and green wires
gives the current value of output 2.
