Hi Guys,
I need to connect a 35W 24V soleniod valve to an S7-200 (CPU 222 DCDCDC) output. I use just this one output of the PLC. The rated current per point (max) for the DC output is 0.75A. As you can see this is not enough for the load of that size.
I cannot interpose a relay too as this is a high speed output (resolution needed to milliseconds) that operates at several hundred times a minute.
When I called Siemens Tech support, they told me to parallel 2 outputs and connect to the valve. This way, they said the output rated current per point would increase to 1.5A. Only condition being the outputs have to synchronize in the program.
Is it this easy to increase the rated current of an output when I have more spare outputs?!
Thanks for your time
