PUB01CB23500V, Control relays and Protection Single-phase Control of Max. or Min. AC/DC (TRMS) Models DUB01, PUB01, PUB01CB23500V, Precise control relays of voltage level max. or min. (adjustable by DIP switches) AC/DC with true effective value measurement (TRMS). Its interlocking function allows the relay output to be activated. The inhibition function is used to prevent the operation of the relay when necessary (maintenance operations or adjustments). LEDs indicate the status of the alarm and output relay., PUB01CB23500V, Dub01 and PUB01 relays measure max. or min. voltages in AC/DC. Example 1 (No connection between terminals Z1, Y1 or 8, 9 - interlock function off) The relay connects when the measured value is above (or below) the pre-selected level for longer than set. Disconnects when the voltage is below (or above) the pre-selected level (see hysteresis), or when the supply voltage is interrupted. Example 2 (Terminals Z1, Y1 or 8, 9 interconnected - interlock function activated) The relay connects and is nailed to the working position when the measured value is above (or below) the pre-selected level for longer than set. When the voltage has fallen below (or exceeded) the pre-selected value, the relay shall connect after opening the contact between the Z1, Y1 or 8, 9 terminals. The relay will also disconnect when interrupting the supply voltage. The yellow LED flashes until the end of the delay period or until the measured value is back within the non-alarm values (see hysteresis). 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.
