Derivative-action element with summing point 2 inputs
DERIVATIVE-ACTION ELEMENT                                                                                                                                                                                                              
Didactic equipment    


This  module  must be suitable for closed loop continuous control systems.
Technical features
•Power supply: +15 V ; 0 V ; -15 V
•Signal voltage range: -10V, ..., +10V
•Coefficient of the derivative action KD = 2 ms .... 2 s
It must be mounted on an insulated didactic module, it must show a schematic diagram and 2 mm terminals for the electrical connection;  three position switch coarse setting, one potentiometer , one integral  action reset input, one switch for inclusion/exclusion of the derivative action and one led indicator of over-range.  It must include also a bus for the supply that allows the connection between the panels.
