5 Inputs
5.1 Universal inputs
Digital signals, passive analog or active analog signals can be connected to
universal inputs.
The device types have the following number of universal inputs: Device type inputs
Switching and monitoring unit:
RMS705B: 8 inputs
Extension modules:
RMZ785: 8 inputs
RMZ787: 4 inputs
RMZ788: 4 inputs
Max. 4 extension modules (selection from 1 RMZ785, 2 RMZ787, and 2 RMX788)
can be connected.
Maximum version
Max. number possible universal inputs:
RMS705B + RMZ785 + RMZ787(1) + RMZ787(2) + RMZ788
8 + 8 + 4 + 4+ 4 = 28 inputs.
5.1.1 Activate function
All inputs are always available. They can be used for display purposes if no longer
used for specific functions.
