Current output coding
With device versions CPM153-AxA/Bxx (2 current outputs) and CPM153-AxC/Dxx (2 current
outputs with HART), the current outputs can be operated as active or passive outputs. Jumpers on
the controller module M3CH allow recoding.
For non-Ex instruments, these modules may be recoded to active outputs.
