Device is new and even was in box recently, but after fire in office - box was in bad condition full of smoke. Maybe will found datasheet if its left in good condition.
Electromagnetic pulse counter 9V120
Also, this product can be called: 9V-120, 9V 120, 9b120, 9v120, 9v-120, 9v 120.
The 9B120 electromagnetic pulse counter is intended for closing the executive electric circuit after counting the required number of electric current pulses (in the range from 5 to 17,000 pulses inclusively) with a frequency of up to 100 pulses per second inclusively.
The counter can also be used to count electric current pulses with a frequency of up to 100 pulses per second inclusive.
Technical characteristics:
The 9V120 counter works from electric current pulses with the following parameters:
- pulse period - not less than 10 ms;
- duration of the pulse at a level not lower than 20 mA - not less than 4 ms;
- pause duration - not less than 5 ms;
- the pulse amplitude is 20 to 50 mA;
- average current value for the period - no more than 20 mA;
- constant component at the moment of no pulse - no more than 0.25 mA.
Coil winding data:
- active resistance - 900±90 Ohm;
- number of turns - 10,000;
- wire diameter 9V120 - 0.1 mm.
The executive electrical circuit switches a current up to 0.2 A at a voltage of 28±4 V.
Overall dimensions - 143x97x105 mm.
Weight - no more than 1.2 kg.
