2 specifications are subject to change without notice (21.10.00) dib02, PIB02 mode of operation dib02 and PIB02 monitor both ac and dc over or under current through an external shunt. when connected with mi or mp current transformer (using the 0.4 to 4 v p range) they can monitor 1-phase or 3- phase ac current up to 500 a. example 1 (connection between termi- nals z1, y1 or 8, 9 - latching function enabled) the relay operates and latch- es 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 intercon- nection between terminals z1, y1 or 8, 9 is interrupted or the power supply is inter- rupted as well. the red led flashes until the delay time has expired or the measured value comes back to a non-alarm value (see hysteresis setting). example 2 (mi ct) (no connection between ter- minals z1, y1 or 8, 9 - latch function disabled) the relay operates when the current flowing in the ct 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 set- ting) or when power supply is interrupted. example 3 (mp ct) (no connection between ter- minals z1, y1 or 8, 9 - latch function disabled - over cur- rent measurement) the relay operates when the maximum current flowing in the ct exceeds the set level for more than the set delay time. it releases when the maxi- mum current drops below the set level (see hysteresis setting) or when power sup- ply 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. power supply overvoltage cat. iii rated operational voltage (iec 60664, iec 60038) through terminals: a1, a2 or a3, a2 (dib02) 2, 10 or 11, 10 (PIB02) 724: 24 vdc 20%, insulated b48: 24/48 vac 15% 45 to 65 hz, insulated b23: 115/230 vac 15% 45 to 65 hz, insulated dielectric voltage dc supply ac supply supply to input 2 kv 4 kv supply to output 4 kv 4 kv input to output 4 kv 4 kv rated operational power ac 4 va dc 3 w supply specifications power on delay 1 s 0.5 s or 6 s 0.5 s reaction time (input signal variation from -20% to +20% or from +20% to -20% of set value) alarm on delay < 100 ms alarm off delay < 100 ms accuracy (15 min warm-up time) temperature drift 1000 ppm/c delay on alarm 10% on set value 50 ms repeatability 0.5% on full-scale indication for power supply on led, green alarm on led, red (flashing 2 hz during delay time) output relay on led, yellow environment (en 60529) degree of protection ip 20 pollution degree 3 (dib02), 2 (PIB02) operating temperature -20 to 60c, r.h. < 95% storage temperature -30 to 80c, r.h. < 95% housing dimensions din-rail version 22.5 x 80 x 99.5 mm plug-in version 36 x 80 x 87 mm weight approx. 150 g screw terminals tightening torque max. 0.5 nm acc. to iec 60947 ce-marking ye s general specifications output spdt relay rated insulation voltage 250 vac contact ratings (agsno 2 ) resistive loads ac 1 8 a @ 250 vac dc 12 5 a @ 24 vdc small inductive loads ac 15 2.5 a @ 250 vac dc 13 2.5 a @ 24 vdc mechanical life 3 30 x 10 6 operations electrical life 3 10 5 operations (at 8 a, 250 v, cos j = 1) operating frequency 7200 operations/h dielectric strength dielectric voltage 3 2 kvac (rms) rated impulse withstand volt. 4 kv (1.2/50 s) output specifications
