– One port provides an SFP‑cage for Small Form‑factor Pluggable transceivers for
single or multi‑mode glass fiber connections.
General purpose control inputs and outputs
– Eight control inputs to receive signals from external systems with configurable
connection supervision.
– Eight voltage free single pole, double throw (SPDT) relay contacts to activate external
devices.

Fault tolerance and supervision
– Supervision of mains, battery and device operation and all connections; faults are
reported to the system controller and logged.
– Automatic battery backup takeover from mains in case of mains failures.
– Multi‑port network interface with RSTP‑support for recovery from a failing network
connection.
