Building Technologies Inputs 18.01.2012
7 Inputs
7.1 Universal inputs (Xx)
7.1.1 General settings
The following signals can be connected to universal inputs:
• Digital signals
•
Passive analog signals.
• Active analog signals.
The following number of universal inputs is available:
RMB795B: 6 inputs.
If more inputs are required, the number can be increased by a maximum of 3
extension modules:
RMZ785: 8
inputs.
RMZ787: 4 inputs.
Hence, the maximum number of inputs is:
RMB795 (6) + RMZ785 (8) + RMZ787 (4) + RMZ787 (4) = 22 inputs.
7.1.2 Activate function
All universal Xx inputs are always available. If not required for their assigned
functionality, they can be used for display.
Inputs that are not required are to be set to "Digital".
To activate, assign a label (identifier) to each input used. The identifier also defines
the input’s unit. The following identifiers are available:
