5-inputs summing point

5-inputs summing point .
This module must consist in a five input summing point; three of them, non inverting; it shall be used in the realization of particular configurations of the controller, using separately the elements P, I and D; the remaining inputs, one inverting and one non inverting, shall be used to add the noise variables.
Technical features:


•Power supply: +15 V ; 0 V ; -15 V
•Signal voltage range: -10V, ..., +10V
•Gain factor = 1
It must be mounted on an insulated didactic module, it must show a schematic diagram and 2 mm terminals for the electrical connection;  oneled indicator of over-range. It must include also a bus for the supply that allows the connection between the panels.
