6-digit preset counters with LC supertwist displays, some in the series are lit & can quantify the incoming pulse with a factor. The forwards & backwards counter switches either at the preset value or when reaching 0. The 2-way display shows the count (8.5 mm high digits) & the preset value (4.5 mm high digits). Wide power supply range, a bi-stable, 1-pin output relay programmable as opener or closer supplies a constant or pulsed (up to 9.9 s) output signal. Easy to read due to supertwist LC display
