the “DCU”.
SDU 410 Safety Unit
The SDU 410 (he
reafter referred to as the “SDU”)
is the
safety unit, which is mandatory in a classed installation. It
is completely self-contained and separate from the DCU.

RIO 410 I/O Expansion Unit
The RIO 410 (hereafter r
eferred to as the “RIO”)
is an
expansion I/O unit. A maximum of four RIO units can be

The DCU communicates with the RIO on a link, and when
connected, the DCU automatically detects the unit and
add it into its configuration.
RIO 425 Generator Interface Unit
The RIO 425 is a generator interface unit. It is linked to
the DCU, which will find it automatically.
When connected, a new page is made available on the
DCU
–
and on the remote panel RP 410
–
that displays
generator parameters such as phase voltages, phase
currents, frequency, power, efficiency factor (Cos phi),
etc.
RIO 412 Exhaust Monitoring Unit
The RIO 412 is a compact unit with 20 thermocouple
channels. Each cylinder’s thermocouple is connected to a
predefined channel on the unit.
The DCU automatically detects the unit, and adds a new
