Wiring of ET 200C; AO 4
12 Bit (6ES7 145-0HF00-0KB0), Continued
The voltage is connected for the load via two high-resistance sensor lines
(S+, S– at terminals
+
and
–
) for each channel. In this way it is possible to
correct voltage drops of up to 3 V per line.
It is important to ensure that the sensor lines are connected directly to the
load.
The illustration below shows how to connect loads in a 4-wire circuit for
voltage output.
