Hi

I have Digital I/Os as follow that i am not sure if i can read by PLC or no. 

1x DI -200 to 800 mv

1x DO -200 to 800 mv 

also, analog signals

1x AI 0-50V

1x AO 0-50A

how can i read them since the PLC is only reading 0-20mA?

Can you help please

Hello,

the easiest way is you use transducer e.g. from Phoenix Contact.
Then can you use the norm signals e.g. 4..20 mA or 0..10 V.

If I understand it right do you nee DI 200 mV = FLASE and 800 mV = TRUE
You can use e.g. the Limit value switches - MINI MCR-2-UI-REL-PT - 2902035

For Analog IN you can use e.g. Signal conditioner - MACX MCR-UI-UI-NC - 2811446

For the digital out can you use a relay or a solid state relay, but you need the switching voltage.
Maybe can you find someone at this website relay module.

What for a signal do you need for your analog out?
A current 0..50 A is only possible with a power supply which is controlled by a analog input or a current source which is controlled by analog signal or bus system e.g. Profinet.

It would be easier to help, if there are more details for the signals and also for the direction. If you write input, do you mean input of the plc or input of the external device ? For digital signals it is necessary to write detailed conditions for high and low signals.
