Diode usage_single or individual per connection needed

[Arul Raju]

Hello,
I would like to know the diodes are really to be connected individually (see Image:1) or a single diode (image:2)is sufficient because they are all sourced from the same 24V. Could anyone suggest me the right solution? I would like to use 1N4007 for this circuit. Please do let me know if you have any questions.

Or suggest me the right diode as well.

Thanks in advance.

Without connection dots on the schematic and more information about the signals involved (voltage range, current, inductive load, etc.) it is almost impossible to say. For example why is the signal on pin 10 labeled just like the ones on 2, 4, 6, and 8, but connected differently?

Here I attached pdf which gives you more details about connection.i have shown UP1 coil activation circuit on the left side, similarly there will be UP2 till UP8 circuit involved which I haven't shown here.

The brake coil rated current is 0.21amps for each motor. And the holding brake rated voltage is 24V DC +/- 10%. The motor output power is 150 W.

The brake release and operation time is 60 and 100 ms respectively. Please do let me know if you need any other information.

Thanks
