Note
Four Pt100-thermocouples can be connected to the CAN/DSUB-Pt100 screw terminals in four-wire
configuration. The necessary feed-current is provided by the imc CANSAS module.
To close the current loop, any non-connected Pt100 units must be replaced with wire bridges:
No Pt100 at Terminals 1+2 -> bridge Terminals 9+10.
No Pt100 at Terminals 3+4 -> bridge Terminals 13+14.
No Pt100 at Terminals 5+6 -> bridge Terminals 17+18.
No Pt100 at Terminals 7+8 -> bridge Terminals 11+12.
