Synco™ 700

Switching and monitoring
device

RMS705B

·

Various switching and monitoring functions combined with mathematical
and physical operations (calculations, minimum, maximum and average
calculations, enthalpy, signal doubler/inverter).

·

Lead/lag control of pumps, fans, motors, refrigeration machines, etc. with
runtime balancing.

·

3 universal controllers with limiting function.

·

Data acquisition: Pulse count (for display purposes), operating hours
count, trend display of data as well as event logging (e.g. for legionella
function).

·

Freely configurable, thanks to extended configuration options.

·

For additional, universal inputs for displaying and monitoring/alarming.

·

Modular extendable with extension modules RMZ785, RMZ787, and
RMZ788.

·

Menu-driven operation with separate operator unit: Plug-in type or
detached mounting.

·

KNX bus connection for operation and process information.
