5. Optional features

5.1 AUX-connection (optional)
Safera PCU6.3 and PCU6.1 power control units Ⓒ are equipped with two auxiliary out-
put signals AUX1 and AUX2 compatible with most automation and security systems.
They can be used to send real-time status information of the stove guard.
5.1.1 Electrical specifications
• Optoisolated and potential-free
AUX-outputs: no galvanic connec-
tion between the Safera system and
the automation system.
• When the AUX outputs are active
(ON), the optoisolator's output tran-
sistors will be held in conducting
mode, thus enabling current flow
from IN to OUT. This connection can
be used exactly as a relay's contact,
however the direction and amount
of the current flow must be con-
trolled as specified below. If neces-
sary, the output states can also be
inversed (see chapter 5.1.6).
• Maximum IN-OUT voltage is 24 VDC.
• Maximum IN-OUT current is 10 mA.
• Only DC voltage between IN-OUT,
no AC is permitted!
