Hi, I’d like to buy the module but also need the circuit that controls an electrical motor (12 Volt/1A), which is controlled by the module. Do you have a kind of circuit in stock?
The circuit should switch off the motor when reaching equal (output is on) and stay off until I switch the motor by pressing a button again on. Then the motor shall keep on running until the module reaches equal and switches the motor again off.
Thanks a lot und best regards from Germany
Sorry, we do not carry such a circuit.
Are we correct that the motor should run at all times, except when the output is ‘equal’?
In this case, a simple MOSFET or relay can do the job.
thank you for your answer.
The motor shall be switched on by the cuicuit I’m looking for via manualy switch. When VM147 signals equal, the motor shall be switched off and keep beeing switched off until I switch the motor on again. A latching relay (in German: Stromstoßschalter) would do. But I can’t find any which is controlled by open collector. All relays I find are switched by shorten to ground.
Could I make myself clear?
sorry, it’s me again. You write, a simple relay can do in case, that the motor should run all the time except in state of equal. This is correct. But as far as I understand does equal only send the control voltage for max 900ms. This means, the motor would start running again after 900ms. If not so, if the control voltage could also be configured to be on for the whole time while equal, that would fit my needs nearly. It doesn’t fit perfectly because the module would reset automatically by reaching equal (as far as I understand) and the control voltage will be shut off again. On the other hand, if automatic reset is configured off, the preset value must be set again and again for every new measuring cycle. Am I correct?
Sorry, you are correct, the VM147 unit only delivers a pulse.
The K8035 counter keeps the output on as long as the value is ‘equal’.
Thank you very much for your help.
