All signals are isolated from the measuring circuit and the ground (earth) (the input/output common
is shared).
The input circuit can be switched for current sink output (NPN) or current source output (PNP).
Check the input rating and internal circuit configuration (p. 179), and then understand the safety
precautions. After that, connect the control system and use it in a correct manner.
