Hi.
I am talking about the 6ES7 523-1BL00-0AA0 module
I want to connect 24VDC programmable timer to the input of this module. The timer supplies up to 2A of current.
I didn't found the maximum limitation for the input current.
Will it be able to manage up to 2A in the input?
Thanks
Hello,
The 6ES7 523-1BL00-0AA0 (SIMATIC ET 200SP, standard I/O, 4-channel 24 V DC input) has a maximum input current of 0.5A per channel and 2A total for the entire module.
Connecting a 24VDC programmable timer supplying up to 2A to a single input channel of this module is not recommended and could potentially damage the module. The timer's current exceeds the per-channel limit.
You will need to use an interface (e.g., a relay or optocoupler) to isolate the timer and reduce the current drawn by the ET 200SP input.
For detailed specifications, refer to the ET 200SP documentation on SiePortal:
ET 200SP System ManualIf you have further questions, please don't hesitate to ask.
