DIA01CB235A Carlo Gavazzi

DIA01CB235A, Control Relays and Protection Single Phase CONTROL of Overintensity CA/DC Models DIA01, PIA01, DIA01CB235A, Precise control relays of AC/DC overintensity. Direct measurement or through intensity transformer. Its interlocking function allows the relay output to be activated. The red LED indicates the status of the relay. Loads up to 5 A AC/DC, DIA01CB235A, DIA01 and PIA01 can be controlled through the internal shunt, AC and DC overintensities can be controlled through an internal shunt. Connected to a suitable current transformer they can control AC currents up to 6000 A. Example 1 (Terminals Z1, Y1 or 8, 9 interconnected - interlock function off) The relay connects and is located in the operating position when the measured value exceeds the pre-selected level. When the measured value falls at least 4% below the pre-selected value (see hysteresis) the relay disconnects when opening the contact between terminals Z1, Y1 or 8, 9, or also when interrupting the supply voltage. Example 2 (standard CT) (Terminals Z1, Y1 or 8, 9 unconnected - activated interlock function) The relay connects when the intensity measured in the transform exceeds the pre-selected level. Disconnect when the intensity drops at least 4% below the pre-selected level (see hysteresis) or when the supply voltage is interrupted.
