Appendix B2: Hardware extension - Analogue outputs
A module incorporating 2 analogue outputs is available as a hardware extension for the 362MC which can
be installed at the factory. The module incorporates the respective D/A converters and the isolated
output stages, which in standard configuration are provided as linear current outputs. Linear voltage out-
puts are also available as a special variant.
Terminal assignments
Connection is carried out by means of
terminals 21-24, which are marked
Module 2, in accordance with the
table opposite. The extension is
available only with 2 x current output
or 2 x voltage output.
Connection and wiring
The diagrams opposite show the connection
configuration. Connection is carried out with
shielded, twisted-pair cabling with a min. wire
cross-section of 0.22mm².
Parameterisation
The outputs are parameterised in the Output
commissioning menu as controller output or
outputs for external actual-value indication,
according to their respective tasks. The output
range 0-20mA / 4-20mA or, with opposite
effective direction 20-0mA / 20-4mA, is
assigned by the user as required. The same
applies to the voltage outputs. The outputs
are defined as unipolar or bipolar outputs via
appropriate parameterisation of the controller
output limiting parameters, Ymin and Ymax.
The following table shows several examples of
definitions for the output range. See also
Controller parameters menu (5.5) and Output menu (5.7).

The shields of all connection cables are to be
connected to control cabinet earth, ensuring a
substantial contact surface area. The cabling
should be as short as possible and have an
adequate cross-section.
