Connecting Loads/Actuators To The Analog Output - Siemens SIMATIC C7-626 Installation, Assembly, Wiring

Connecting Loads You must connect loads to a current output at Q
to a Current
the analog circuit M
Output
Figure 6-5 shows the principle of connecting loads to a current output of an
isolated analog output module.
Figure 6-5
Connecting Loads
Connection of loads to a voltage output is only possible in 2-wire circuits as
to a Voltage
there is only one output.
