Measurement
stop when the
main preset
reached
(1) The measurement starts on the rising edge of the state applied to input A and stops on the
falling edge.
(2) The measurement starts on the rising edge of the pulse and stops on the rising edge of the
Stop pulse.
(3) On each Start pulse, the measurement starts again at 0.
(4) For counters with only one preset P1, the corresponding output is OUT1.

DESCRIPTION
- Accumulated time duration while input A is
active (1)
- Accumulative time duration between 2 rising
edges on A (2)
- Time duration while input A is active (1), (3)
- Time duration between 2 rising edges (2), (3)
- No transmission (if external reset before P2 is
reached, the output is not activated) (4)
- With transmission OUT2 on reset (In the
event of reset on OUT2 the output is activated)
(4)
HTL inputs for NPN (sensitive to a level "0"
y c 2 V and "1" u c 8 V)
- HTL inputs for PNP (sensitive to a level "0"
y c 2 V and "1" u c 8 V)
- TTL inputs for NPN (sensitive to a level "0"
y c 2 V and "1" u c 3.8 V)
- TTL inputs for PNP (sensitive to a level "0"
y c 2 V and "1" u c 3.8 V)
- Attenuation at 30 Hz (to avoid contact bounce
being taken into account)
- No attenuation (5 KHz or 2.5 KHz if two-way
counting)
- Static: no counting during resetting time
- Dynamic: counting possible during resetting
time
- No saving of outputs after power cut
- With saving of outputs after power cut
- Without
- With (provides an indication of the time
duration even reset is/has been activated
- No stop
- Measurement stop when the main preset is
reached.
