Assortment / System Description

Extension modules RMZ78x

The RMZ78x extension modules (see Data Sheets N3136 and N3146) are used to

extend the scope of functions of the Synco 700 controls RM.. and to increase the

number of inputs and outputs.

• Extension modules can only be attached to Synco 700 controls RM.. (cannot

operate autonomously)

• Extension modules are ready to operate as soon as they are connected to one

of the controls

• The modules are powered via the controls

• The modules are identified and monitored by the controls

• The exchange of data between extension modules and controls is executed by

the controls. This means that the signals from the sensors, signal sources, etc.

are fed to the control where they are handled. The output signals and switching

commands generated by the control are forwarded to the respective extension

module

• Use of the extension modules (types and numbers) depends on the type of

Synco 700 control
