Inputs and outputs
The number of inputs and outputs of the Synco 700 controls RM.. differ. Also, the
characteristics of the universal inputs are not the same (e.g. input N.X_ configur-
able/nonconfigurable for pulse signals).

The universal inputs N.X_ can be configured for analog signals of passive sensors
or active signal sources using the measuring variables °C, %, g/kg, kJ/kg, W/m

bar, mbar, m/s, Pa, ppm, or for status signals. Signal types:
• LG-Ni1000, 2 x LG-Ni1000 (averaging), Pt1000, and T1
• 0…1000 Ω, BSG21.1 (setpoint, absolute), 0...1175 Ω, BSG21.5 (setp., relative)
• DC 0...10 V
• Status contact, potential free
Depending on the type of control, the universal inputs N.X_ can be configured for
the following types of pulse sources:
• Mechanical pulse source (Reed contact), pulse frequency max. 25 Hz
• Electronic pulse source (Open Collector), pulse frequency max. 100 Hz
The analog outputs N.Y_ and relay outputs N.O_ are ready configured for the
following types of signals:
• Analog: DC 0...10 V/1 mA
• Relay contacts: Potential free, for switching AC 19…250 V, max. 4 (3) A
Depending on the activated type of application, the controls have certain inputs and
outputs assigned or nonassigned. For extensions (e.g. extra sensors), only
nonassigned inputs and outputs can be configured.
The number of inputs and outputs can be increased by attaching extension
modules to the RM.. controls (see page 57).
With the Synco 700 controls RMU7x0B, RMS705B and RMB795B, universal data
exchange can be configured via the controls’ own input and output terminals or via
the terminals of the RMZ78x extension modules. Data exchange between the
controls is the same as if the terminals were wired.
The digital and analog outputs are used as transmit objects in transmission zones,
and the universal inputs as transmit objects or reception objects in reception
zones.
It is possible to have a maximum of 32 universal transmit and reception zones per
line. Data exchange between the zones takes place via KNX in LTE and S-mode.
Universal transmit and reception zones are not permitted in the following cases:
• On safety-related applications such as smoke extraction, frost protection, or
when communication breakdown can cause damage
• With time-critical controlled systems having a high degree of difficulty
