Second  Order  Transfer   Element

DL 2677

Module DL 2677 allows to analyze the behaviour of an element with proportional transfer function able to oscillate, with a delay of the second order, both in the time domain and in the frequency domain.

Power supply: +15 V ; 0 V ; -15 V
Signal voltage range: -10V, ..., +10V
Gain factor = 1
Time constant T = 10 ms .... 30 s, selectable through two rotary switches
Damping coefficient d = 0 .... 3, with potentiometric setting
Reset input for the restoration of the initial conditions
Leds indicators of over-range

Description
1. Terminal for the input signal
2. Terminal for the output signal
3. Input Ioff for the restoration of the initial conditions:
Ioff < 4 V : reset and restoration of the initial conditions;
Ioff > 8 V or disconnected: delay elements active
4. Rotary switches for the selection of the time constant T
5. Potentiometer for the continuous setting of the damping coefficient d
6. Led "over" on when the output voltage is higher than 10 V or lower than -10 V
