due to a fault (e.g. power supply unit failure, tripped fuse), the corresponding relay
is de-energized. The green “IN 1“ and “IN 2“ LEDs light up when the voltage
exceeds the set threshold value. The green “OUT“ LED lights up when the output
voltage is > 3 V.

SENSE OUT
The SENSE OUT + + - terminals are arranged
at the + and - potential on the output side and
can be used for signaling purposes.
INPUT 1 (IN 1)

Potential-free change-over contact
11-14 closed and 11-12 opened when the
voltage in channel 1 (IN 1) of the CP-A RU
exceeds the threshold value set at “IN 1 <V“.
11-12 closed and 11-14 opened when the
voltage in channel 1 (IN 1) of the CP-A RU is
lower than the threshold value set at “IN 1 <V“.
INPUT 2 (IN 2)
OK message
Potential-free change-over contact
21-24 closed and 21-22 opened when the
voltage in channel 2 (IN 2) of the CP-A RU
exceeds the threshold value set at “IN 2 <V“.
21-22 closed and 21-24 opened when the
voltage in channel 2 (IN 2) of the CP-A RU is
lower than the threshold value set at “IN 2 <V“.
