DIB01CM24100A

Monitoring Relays 1-Phase True RMS AC Over or Under Current Type DIB01 100A • TRMS AC over or under current monitoring relay • Current measuring through built-in current transformer • Selection of measuring range by DIP-switches • Measuring ranges from 2 A to 100 A AC • Adjustable current 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 • 22.5 mm Euronorm housing • LED indication for relay, alarm and power supply ON • Galvanically separated power supply Product Description Ordering Key DIB01 is a precise TRMS AC over or under current (selectable by DIP-switch) monitoring relay. Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay Housing Function Type Item number Output Power supply Measuring range operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay. Through the built-in current transformer it is possible to monitor loads up to 100 A AC.

Example 1 (connection between terminals A1, Y1 - latching function enabled - Relay ND) 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. Provided that the current has dropped below (or has exceeded) the set point (see hysteresis setting), the relay releases when the interconnection between terminals A1, Y1 is interrupted or the power supply is interrupted as well. The red LED flashes until the delay time has expired. Example 2 (no connection between terminals A1, Y1 - latch function disabled - Relay ND) 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 current drops below (or exceeds) the set level (see hysteresis setting) or when power supply is interrupted. 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. Function/Range/Level and Time Delay Setting Adjust the input range setting DIP switches 1 and 2 as shown below. Select the desired function setting DIP switches 3 to 6 as shown below. To access the DIP switches open the grey plastic cover as shown below. Selection of level and time delay: Upper knob: Setting of hysteresis on relative scale: 0 to 30% on set value. Centre knob: Current level setting on relative scale: 10 to 110% on full scale. 2 Lower knob: Setting of delay on alarm time on absolute scale (0.1 to 30 s).
