The KU/D2 transmitter is designed to control systems requiring control of digital signals by means of 0-10V analog voltage signal. It is equipped with two independent normally-open (NO) relay outputs, the activation of which depends on the threshold value adjusted by potentiometers Prog1 and Prog2, respectively. When the input voltage exceeds the threshold value, the corresponding relay contact will switch on. The relay is deactivated when the input voltage value drops by the amount of hysteresis (1.5V) below the threshold.
