DIA01CD485A Carlo Gavazzi

DIA01CD485A, Control Relays and Protection Single Phase OVERINTENS AC/DC Overintensity Models DIA01, PIA01, DIA01CD485A, Precise AC/DC Overintensity Control Relays. 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, DIA01CD485A, DIA01 and PIA01 can be controlled through the internal shunt, AC and DC over-tensions 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.
