DHB Series Panel digital instruments which display on-screen, depending on the model, the value of a measured electrical variable or the proportional value of a process signal. Designed for supervision, regulation and control, through the use of analogue outputs and relays, integrated in the unit. The DHB series enables full configuration of scales, transformation ratio, alarm setpoints, changes in colour of the display, communications, etc. Depending on the model, the unit shows the electrical parameters of a single-phase installation, such as voltage, current, frequency, power, cos φ,...
