Monitoring Relays 1-Phase True RMS AC/DC Over or Under Voltage Types DUB01, PUB01 DUB01 • TRMS AC/DC over or under voltage monitoring relays • Selection of measuring range by DIP-switches • Measuring ranges from 0.1 to 500 V AC/DC • Adjustable voltage on relative scale • Adjustable hysteresis on relative scale • Adjustable delay function (0.1 to 30 s) • Programmable latching or inhibit at set level • Output: 8 A SPDT relay N.D. or N.E. selectable • For mounting on DIN-rail in accordance with DIN/EN 50 022 (DUB01) or plug-in module (PUB01) • 22.5 mm Euronorm housing (DUB01) or 36 mm plug-in module (PUB01) • LED indication for relay, alarm and power supply ON PUB01 Product Description DUB01 and PUB01 are precise TRMS AC/DC over or under voltage (selectable by DIP-switch) monitoring relays. Owing to the built-in latch function, the ON-position of the relay output can be Ordering Key maintained. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay.

Example 1 (no connection between terminals Z1, Y1 or 8, 9 - latch function disabled) Example 2 (connection between terminals Z1, Y1 or 8, 9 - latch function enabled) The relay operates when the measured value exceeds (or drops below) the set level for more than the set delay time. It releases when the voltage drops below (or exceeds) the The relay operates and latches in operating position when the measured value exceeds (or drops below) the set level for more than the set delay time. 2 Provided that the voltage has dropped below (or has exceeded) the set point (see hysteresis setting) the relay releases when the interconnection between terminals Z1, Y1 or 8, 9 is interrupted, or power supply is interrupted as well. The yellow LED flashes until the delay time has expired or the measured value has dropped below the set point (see hysteresis setting). Note When the inhibit contact is opened, if the input signal is already in alarm position, the delay time needs to elapse before relay activation.
