4.1.3.5.2 Analog outputs
The controller generates signals with standardized values of 0 …+10 V for the
field range.
The product has 2 output channels, making two 2-wire actuators possible.
The actuators are connected via the AO1 and ground connections or AO2 and
ground.
The channels have a common ground potential.
The output signal is output at a resolution of 12 bits.
The internal power supply powers the module.

4.1.3.6 Communication Interface
The communication interface integrated in the controller allows devices with an
RS-485 interface to be connected.
The D +, D-, GNDRS and SHRS connections are used for wiring to the
communication partner.
The shield connection directly connects to the DIN-rail.
The interface operates in accordance with DIN 66259.
The connected device can communicate directly via the controller used. The
active communication channel works independently of the higher-level bus
system in half-duplex mode at up to 115200 baud.
The RS-485 interface guarantees a high level of interference immunity through
differential transmission and electrically isolated signals.
