3.4.2 Connecting current outputs
Note: Only use screened cable for
the current outputs to exclude the
possibility of external
interference. Only connect the
screen to earth at one end.
The controller has two separate current outputs (1 and 2). The two current outputs
(0/4-20 mA, max. 500 Ohm) transmit one or both measured values depending on
the setting in the program.
