DL 2679

Two Position Controller

DL 2679

Module DL 2679 is a two position controller for discontinuous closed loop control systems.
It is provided with an input summing point to which the reference variable (non inverting input) and the controlled variable (inverting input) are connected.
By means of two leds the binary state of the controller, whose hysteresis can be changed, is visualized.
The controller is provided with two binary outputs at different voltages.
