PUC01CD48500V, Control relays and Protection Single-phase Voltage Control Max. and Min. AC/DC, TRMS Models DUC01, PUC01, PUC01CD48500V, Precise control relays of maximum voltage levels + minimum, maximum + - maximum or minimum + minimum (selectable by DIP switches), with TRMS measurement. Voltage levels are adjusted separately and have their own delay. 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). The LEDs indicate the status of the alarm and the output relay., PUC01CD48500V, The DUC01 and PUC01 equipment allow to control the voltage level max.+min., max.+max. or min.+min. in AC and DC. Example 1 Non-contact input - min.+max voltage - 2 normally activated SPDT relays (1 SPDT relay for the PUC01 model) DUC01: A relay connects when the voltage remains below the pre-selected minimum voltage value for a time longer than the adjusted delay period. Disconnect when the voltage exceeds the pre-selected level plus the adjusted hysteresis. The other relay connects when the voltage exceeds the pre-selected maximum voltage level for a time longer than the corresponding delay period. Disconnect when the voltage drops below the selected level minus hysteresis. PUC01: The relay connects when the voltage remains below the pre-selected minimum level for a time longer than the corresponding adjusted delay period, or when it exceeds the pre-selected maximum voltage level for a time longer than the adjusted lat. The relay disconnects when the voltage exceeds the pre-selected minimum voltage level plus hysteresis or is below the adjusted maximum voltage level minus hysteresis (hysteresis is the same for both levels). Example 2 (Active interlock function - min voltage + min. - 2 SPDT relays (1 SPDT relay for the PUC01 model) DUC01: Each relay connects and is nailed when the voltage falls below the selected level for a longer time than its corresponding delay period. When the voltage exceeds the pre-selected level plus hysteresis, each of the relays will disconnect after the connection of the contact input is interrupted. PUC01: The relay connects when the voltage remains below the selected maximum level for a longer time than the adjusted delay period. When the voltage exceeds the pre-selected maximum level plus hysteresis, the relay disconnects when the contact input is opened Example 3 (Active inhibition function - max voltage +max - DPDT relay (SPDT for the PUC01) When opening the contact input, the relay connects when the voltage exceeds the pre-selected minimum level for a time longer than the adjusted delay. Disconnect when the voltage is below the minimum level minus hysteresis or when the contact input pins are interconnected. Note When the inhibition contact is open and the input signal is in the alarm position, the relay (the relays) will not be activated until the delay period has elapsed.
