2.6.3 Connect analog output
All easy800 standard devices with a 24 V DC supply voltage have an analog
output QA 01. QA 01 can be used to output a DC voltage from 0 - 10 V, with
a 10-bit resolution, value range 0 - 1023.
On the easy800 standard from device version 02, it is also possible to
connect the EASY406-DC-ME and EASY411-DC-ME DC expansion units with
an analog output (
￫
Section “Connecting DC inputs of the EASY4..-DC-ME
expansion units“, Page 39).
The analog output can be used, for example, for controlling solenoid valves
and other actuators.
Observe the hazard warnings concerning the processing of analog signals
(
￫
section 2.5.2, “Connecting analog inputs”, page 40) and the note
concerning the same reference potential (chassis ground).
