Fig. 5.1.8.2.-2 Double-pole power outputs (PO)
If the power outputs BIO2_7_PO3... BIO2_7_PO6 are used as single-pole outputs,
the object to be controlled is electrically connected in series with the two relay
contacts to provide sufficient breaking capacity, see the following figure.

Signal outputs (SO)
The signalling relay outputs (BIO1_5_SO_) are not heavy-duty outputs and thus
they cannot be used for controlling for example a circuit breaker. Available relay
contacts are either Normally Open or Normally Open/Normally Closed type (NO or
NO/NC), see the following figure. These outputs can be used for alarming and other
signalling purposes.
