10.2.1.2. Analog outputs
The mA outputs are connected to terminal block X 5
The maximum loop resistance for the mA outputs is 500 Ohms with signal isolation.
If more than three current outputs are required, additional DC/DC isolation modules
will be required for each output.
A maximum of seven analog outputs are available, up to three are supplied as
standard. The functional position of the current outputs can be user selected using
the Analog output menu and the standard delivery configuration is shown below.
