We are looking for Probes etc. to attach to the MD888+ Super PLC. Now, we found a lot of different Input Signal types like 4-20mA, 1-5V,1-10V and much more. What are the best or lets say easiest Input Signals to handle with the PLC? What we see is that we may must be able to use the 4-20mA Signal for some Sensors (2Wire, at least 4x). Can you advise us? Thanks in advance
