Inputs 1 to 5 all have the same function and mode of operation
except for terminal 5, which can also be configured as thermistor
input.
Inputs 1 to 5 are optically and electrically isolated from the built-
in control section (CPU). They are actuated with +24 V. You can
use the device’s internal control voltage from terminal P24 or an
external voltage source.
You can configure the actuation of inputs 1 to 5 for special control
circuits and national circuit types Table 11 shows the various
versions in dependence of the SR/SK microswitch. This switch is
located to the right of the control signal terminals and has two
switching contacts:
• SR = source, positive switching logic (default settings)
• SK = sink, negative switching logic

Warning!
Before you switch on the internal or external control
voltage, check the position of the SR/SK switch. An
incorrect setting can damage the control input.
