I am looking for converting device between 5V TTL, such as USB-6501 DIO signal, and 24DCV used in PLC DIO.
I use PLC to control test system, and use PC for DAQ.
By analyzing DAQ data, I need to cut into control sequence.
Also I like to keep records of system status, such as pump and motor running signals.
I like to communicate with PLC through DIO signals, so that, I do not need to care which manufacture or what model used.
I like to purchase converter board, not making one.
