DIB71CB485A Carlo Gavazzi

DIB71CB485A, Control Relays and Protection Control monophas. max. or min. AC/DC intensity, TRMS Model DIB71, DIB71CB485A, Precise control relays max. or min. level (adjustable by DIP switches) AC/DC intensity, with True Effective Value Measurement (TRMS). Its interlocking function allows the relay to be kept activated. The inhibition function is used to prevent the operation of the relay when necessary (maintenance operations or adjustments). The LEDs indicate the status of the alarm and the output relay. The built-in shunt allows you to control loads of up to 5 A AC / DC. 35.5 mm case suitable for mounting on mudular or industrial panels., DIB71CB485A, DIB71 equipment is used to control the maximum level or min. of AC and DC intensities. Example 1 (Interconnected Z1, Y1 terminals - activated interlock function) The relay connects and is stuck in the working position when the measured value exceeds (or falls below) the pre-selected level for longer than the adjusted delay period. To unlock open the Z1 and Y1 terminals, or interrupt the supply voltage. The red LED will flash until the end of the delay period or until the measured value is back within the non-alarm values (see adjusted hysteresis). Example 2 (standard CT) (No connection between terminals Z1, Y1 - interlock function disabled) The relay connects when the measured value is above (or below) the pre-selected level for longer than the adjusted delay period. Disconnects when the measured intensity is below (or above) the pre-selected level (see adjusted hysteresis) or when the supply voltage is interrupted. Note When the inhibition contact is open and the input signal is in the alarm position, the relay will not activate until the delay period has elapsed.
