DIB01CD48500MA, Control Relays and Protection Control Single Phase Intensity Max. or Min. AC/DC, TRMS Models DIB01, PIB01, DIB01CD48500MA, Max./Min. Current Level Control Relays (selectable by DIP switches) of AC/DC, with True Effective Value Measurement (TRMS). They measure directly or through an intensity transformer. Its interlocking function allows the relay output to be activated. The inhibition function can be 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 internal shunt allows to control loads of up to 10 A AC / DC., DIB01CD48500MA, The DIB01 and PIB01 equipment control the level of the maximum or minimum intensity, both in alternating and direct current, through an internal shunt. Example 1 (Terminals Z1, Y1 or 8, 9 interconnected - activated interlock function) The relay connects and is nailed to the working position when the measured value exceeds (or falls below) the pre-selected level for a time longer than the adjusted delay period. When the intensity falls below (or exceeds) the selected value (see hysteresis), the relay disconnects when the contact between the Z1, Y1 or 8, 9 terminals is opened or when the supply voltage is interrupted. 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 hysteresis). Example 2 (standard CT) (Terminals Z1, Y1 or 8, 9 unconnected - interlock function disabled) The relay connects when the measured value exceeds (or falls below) the pre-selected level during a delay period greater than the selected one. Disconnects when the intensity falls below (or exceeds) the pre-selected level (see 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.
